Lamy M16/M17 Ballpoint Refill Overview
The Lamy M16 Refill is the standard proprietary ballpoint refill used in many of Lamy’s most popular full-size ballpoint pens. It is the classic replacement refill for pens such as the Lamy Safari ballpoint, AL-star ballpoint, Lamy 2000 ballpoint, Studio ballpoint, Logo ballpoint, Aion ballpoint, CP1 ballpoint, and other compatible Lamy ballpoint models.
The Lamy M17 Refill is the main modern upgrade option for many of those same pens, especially for users searching for a smoother Lamy M16 refill alternative. It is designed to fit Lamy pens that accept the M16 refill, but it uses Uni Jetstream hybrid ink instead of the traditional oil-based ballpoint ink used in the M16. For users who love the design, weight, and durability of Lamy ballpoint pens but want a smoother, darker, lower-friction writing experience, the M17 may be the best modern Lamy M16 refill alternative.
Together, the M16 and M17 give Lamy ballpoint users two very different writing choices in the same general refill format. The M16 remains the standard original refill with broad color and tip-size options. The M17 brings Jetstream-style hybrid ink performance to compatible Lamy ballpoint pens, making it a major upgrade for users who have historically found the M16 too dry, light, or draggy.
Lamy M16 vs M17: What’s the Difference?
The main difference between the Lamy M16 Refill and the Lamy M17 Refill is the ink. The M16 is Lamy’s traditional proprietary oil-based ballpoint refill. The M17 uses Uni Jetstream hybrid ballpoint ink, which is known for a smoother feel, darker line, and lower writing friction than many standard ballpoint inks.
| Feature | Lamy M16 Refill | Lamy M17 Refill |
| Ink Type | Traditional oil-based ballpoint | Uni Jetstream hybrid ballpoint |
| Writing Feel | Standard ballpoint feel; can have slight drag | Smoother, lower-friction glide |
| Line Darkness | Standard ballpoint line | Darker, more saturated black line |
| Drying Time | Standard ballpoint drying | Fast-drying hybrid ink |
| Tip Sizes | Extra Fine, Fine, Medium, Broad | Extra Fine 0.5 mm, Fine 0.7 mm |
| Ink Colors | Black, Blue, Red, Green | Black only |
| Lifespan | Long | Usually shorter than the M16 because of smoother, wetter ink flow |
| Best For | Original Lamy compatibility, color options, and long refill life | Smoother writing and the best modern M16 upgrade |
If you want the original Lamy writing experience, need blue, red, or green ink, or want the longest refill life, the Lamy M16 Refill is still the safest choice. If you want the smoothest writing experience currently available in an M16-compatible refill, the Lamy M17 Refill is the more interesting option.
Why Choose the Lamy M16 Refill?
Choose the Lamy M16 Refill if you want the original manufacturer refill for a compatible Lamy ballpoint pen. It is widely available, long-lasting, and offered in more colors and tip sizes than the newer M17. For many users, the M16 is still the most practical everyday refill because it is easy to find and gives a predictable traditional ballpoint writing experience.
The Lamy M16 Refill is also the better choice if you need blue, red, or green ink. The M17 is currently much more limited, while the M16 remains the standard option for users who need multiple ink colors, broader tip choices, or a straightforward replacement for the refill that came with the pen.
Why Choose the Lamy M17 Refill?
Choose the Lamy M17 Refill if you like your Lamy ballpoint pen but want a smoother, darker, more modern writing experience. The M17 is designed for pens that accept the Lamy M16 Refill, but it uses Uni Jetstream hybrid ink instead of traditional ballpoint ink. That makes it one of the most important upgrades available for Lamy ballpoint users.
The M17 is especially appealing for people who love the body of a Lamy Safari, AL-star, Studio, 2000, Logo, or other compatible Lamy ballpoint but have never loved the standard M16 writing feel. It offers lower writing friction, darker black ink, and a smoother glide while still keeping the same Lamy pen body.
The tradeoff is availability and variety. The Lamy M17 Refill may be harder to find than the M16, is currently much more limited in color selection, and may not last as long because smoother hybrid ink typically flows more freely than standard ballpoint ink.
Writing Characteristics
The Lamy M16 Refill has a traditional oil-based ballpoint writing feel. It writes cleanly and reliably, but compared with hybrid refills, it can feel firmer and slightly drier. This makes it a practical refill for everyday notes, forms, signatures, office writing, and users who prefer a controlled ballpoint line.
The Lamy M17 Refill writes very differently. Because it uses Uni Jetstream hybrid ink, it is smoother, darker, and lower-friction than the standard M16. It offers a more fluid writing feel without behaving like a wet rollerball. For many users, the M17 makes Lamy ballpoint pens feel more modern and more enjoyable for longer writing sessions.
The M16 is best for users who value long life, color choice, and the original Lamy refill experience. The M17 is best for users who want the smoothest writing upgrade for an M16-compatible Lamy pen.
Compatible Pens
The Lamy M16 Refill is used in many full-size Lamy ballpoint pens. The Lamy M17 Refill is designed for pens that accept the M16 refill, making it an important upgrade option for many of the same models.
Common compatible pens may include:
- Lamy Safari Ballpoint Pen
- Lamy AL-star Ballpoint Pen
- Lamy LX Ballpoint Pen
- Lamy Vista Ballpoint Pen
- Lamy 2000 Ballpoint Pen
- Lamy Studio Ballpoint Pen
- Lamy Logo Ballpoint Pen
- Lamy Aion Ballpoint Pen
- Lamy CP1 Ballpoint Pen
- Lamy Accent Ballpoint Pen
- Lamy Scala Ballpoint Pen
- Other Lamy ballpoint pens designed for the M16 refill
Always confirm your specific pen model before purchasing. Lamy makes several refill types, and the M16/M17 format is not the same as Lamy M21, Lamy M22, Lamy M63, Lamy M66, Parker Style G2, Pilot G2, or D1 Mini refills.
Compatible Brands
The Lamy M16 Refill and Lamy M17 Refill are primarily designed for compatible Lamy ballpoint pens. This is a proprietary Lamy refill shape, so compatibility outside of Lamy is much more limited than it is with Parker Style G2 or D1 Mini refills.
Brands and pen types commonly associated with this refill format include:
- Lamy
- Lamy Safari ballpoint pens
- Lamy AL-star ballpoint pens
- Lamy 2000 ballpoint pens
- Lamy Studio ballpoint pens
- Lamy Logo ballpoint pens
- Lamy Aion ballpoint pens
- Select third-party pens specifically designed for Lamy M16-style refills
Do not assume that a Parker Style G2 refill, Pilot G2 refill, D1 Mini refill, or standard rollerball refill will fit a Lamy M16-compatible pen. The M16/M17 shape is proprietary and must be replaced with a refill specifically made for that format.
Lamy M16 Refill Alternatives
The Lamy M16 Refill is proprietary, so alternatives are more limited than they are with open refill formats like Parker Style G2 or D1 Mini. However, there are now a few useful options for users who want something different from the standard M16.
The most important Lamy M16 refill alternative is the Lamy M17 Refill. It is designed for M16-compatible Lamy pens and uses Uni Jetstream hybrid ink for smoother, darker writing. This makes it the most direct upgrade for many users who want better writing performance without modifying the pen.
Other possible alternatives may include aftermarket refills made specifically for Lamy M16-compatible pens, such as Monteverde Soft Roll refills for Lamy ballpoint pens or Jaymo replacement refills marketed for Lamy M16-style pens. Some users also experiment with refill hacks or adapters, but those should be treated as advanced options rather than simple drop-in replacements. For more information on Lamy M16 Refill Alternatives and experimental options, including how some users modify Parker-style G2 refills to help make up the 8 mm length difference, read our Best in Ink article: Best Lamy M16 Refill Alternatives and How to Modify a Parker-Style G2 Refill.
Popular alternatives include:
- Lamy M17 Jetstream Refill
- Monteverde Soft Roll Refill for Lamy Ballpoint Pens
- Jaymo Replacement Refill for Lamy M16-Compatible Pens
- Specialty refill adapters, where available
- Refill hacks, for users comfortable with modifications
For most users, the M17 is the cleanest upgrade because it is designed around the Lamy M16-compatible format. The Monteverde and Jaymo options may be useful if you want a different price point, color option, or writing feel, but fit and performance should be checked carefully before buying in quantity.
Refill Family
The Lamy M16 and M17 belong to the larger Lamy M-series refill family, but they should not be confused with other Lamy refill numbers. The M16 is the standard full-size ballpoint refill for many Lamy ballpoint pens. The M17 is the Jetstream hybrid ink upgrade for M16-compatible pens.
Other Lamy refills serve different purposes. The Lamy M21 is a compact D1-size refill for many Lamy multi-system pens. The Lamy M22 is a shorter compact ballpoint refill used in select small Lamy pens. The Lamy M63 and Lamy M66 are rollerball refills. These refills are not interchangeable with the M16 or M17.
Within the Lamy ballpoint world, the M16 is the traditional standard and the M17 is the performance upgrade. If you are replacing a refill in a full-size Lamy ballpoint pen, those are the two refill names to know first.
How to Identify a Lamy M16 or M17 Refill
The Lamy M16 Refill and Lamy M17 Refill use a proprietary Lamy ballpoint refill shape. They are larger than D1 Mini refills and shaped differently from Parker Style G2 and Pilot G2 refills.
Key identification points:
- About 106 mm long
- Proprietary Lamy ballpoint refill shape
- Metal refill body
- Distinctive wide center section
- Used in many full-size Lamy ballpoint pens
- M16 is the traditional Lamy ballpoint refill
- M17 is the Jetstream hybrid ink version for M16-compatible pens
- Not the same as Lamy M21, M63, or M66
- Not the same as Parker Style G2, Pilot G2, or D1 Mini
If you are replacing a refill in a Lamy ballpoint pen, check the refill number printed on the existing refill and compare the shape carefully. If your pen currently uses a Lamy M16 Refill, the M17 may be a compatible upgrade option. If your pen uses a smaller Lamy refill such as M21, the M16 and M17 are not the right replacement.
