The best Lamy M63 refill alternatives depend on how much experimenting you are willing to do. The Lamy M63 rollerball refill is a 115 mm refill used in many capped Lamy rollerball pens, but some writers prefer to modify other refills for a smoother gel feel, a different tip size, or easier availability.
If you want the safest replacement, use the original Lamy M63. If you are willing to experiment, refills like the Pilot G2, Pentel EnerGel, Schmidt 888, and Schmidt 5888 may be worth exploring.

Fit is not guaranteed. These alternatives usually require some trial and error, and you may need a spacer, spring, plastic plug, paper shim, or other small adjustment to get the refill to sit correctly inside the pen.
Why Lamy M63 Alternatives Are Tricky
The Lamy M63 is a proprietary rollerball refill. It is commonly associated with capped Lamy rollerball pens, including models such as the Safari rollerball, AL-Star rollerball, Studio rollerball, and Lamy 2000 rollerball.
The issue is that many popular gel refills are not the same length or shape as the Lamy M63. A refill may slide into the pen body but still sit too far back, create tip wobble, fail to reach the paper properly, or feel loose when writing.
That is why many Lamy M63 refill alternatives are really spacer hacks rather than true drop-in replacements. The refill may be close enough to experiment with, but it still needs help sitting in the correct position.
Quick Comparison: Best Lamy M63 Refill Alternatives
| Option | Best For | Drop-In Fit? | Notes |
|---|---|---|---|
| Lamy M63 Rollerball Refill | Safest replacement | Yes | Original refill for capped Lamy rollerball pens |
| Pilot G2 Refill | Popular gel hack | No | Often reported with a spacer |
| Pentel EnerGel Refill | Smooth gel writing | No | Often tried with a spacer or shim |
| Schmidt 888 Rollerball Refill | Rollerball-style alternative | Not guaranteed | May require a spacer |
| Schmidt 5888 Rollerball Refill | Metal-body rollerball option | Not guaranteed | Similar category to Schmidt 888 |
Best Safe Option: Lamy M63 Rollerball Refill
The original Lamy M63 rollerball refill is the best option if you want the pen to work as intended. It is the safest choice for capped Lamy rollerball pens because it is designed for the pen body, cap, nose cone, and internal refill length.
This may not be the most exciting option, especially if you want gel ink or a smoother writing feel, but it avoids the uncertainty of hacks and modifications. If your pen is new, valuable, sentimental, or something you do not want to risk damaging, the Lamy M63 is the refill to use.
Best for: Reliable fit
Fit type: Direct replacement
Bottom line: Use the M63 if you do not want to experiment.
Pilot G2 Refill Hack
The Pilot G2 refill is one of the most commonly discussed Lamy M63 refill alternatives. It appeals to writers because Pilot G2 refills are easy to find, available in multiple tip sizes, and offer a familiar gel writing experience.
The Pilot G2 is not a direct Lamy M63 replacement. It is usually shorter than the Lamy M63 setup requires, so users often add a small spacer behind the refill to push it forward inside the pen. Without the spacer, the tip may not extend properly or may feel unstable while writing.
Common spacer ideas include a small wad of paper, a piece of plastic tubing, a spring from another pen, or a small plug placed behind the refill. The goal is to fill the extra space behind the refill without forcing the pen closed or putting too much pressure on the tip.

Best for: Easy-to-find gel refill experiments
Fit type: Spacer hack
Bottom line: One of the most popular Lamy M63 alternatives, but not guaranteed.
Pentel EnerGel Refill Hack
The Pentel EnerGel refill is another popular option for Lamy M63 refill experiments. EnerGel refills are known for smooth writing, dark lines, and quick-drying gel ink, which makes them appealing if you want a smoother writing experience than the stock M63.
Like the Pilot G2, the EnerGel is not a true drop-in Lamy M63 refill alternative. It may fit into some capped Lamy rollerball bodies, but it usually needs a spacer or shim to sit correctly. Some users also report tip wobble, so the final feel may depend on the specific pen model, refill size, and spacer method.
If you are experimenting with Lamy M63 alternatives because you want a smoother gel refill, the Pentel EnerGel is one of the most promising options to test.

Best for: Smooth gel writing
Fit type: Spacer hack
Bottom line: A strong option if you like EnerGel ink and are willing to adjust the fit.
Schmidt 888 Rollerball Refill Hack
The Schmidt 888 rollerball refill is a 111 mm rollerball refill that may be useful for Lamy M63 experiments. Since the Lamy M63 is about 115 mm, the Schmidt 888 is still shorter, but the difference is smaller than with many gel refills.
That shorter length still matters. You may need a small spacer behind the Schmidt 888 to help it sit correctly in a capped Lamy rollerball pen. Some users report good results with Euro-style rollerball refills in Lamy rollerball bodies, but fit can vary by model.
The Schmidt 888 is worth considering if you want a rollerball-style refill rather than a gel refill. It may feel closer to the original Lamy rollerball experience than a Pilot G2 or EnerGel hack.
- Buy Schmidt 888 Rollerball Refills 0.5 mm Fine Tip: Black, Blue, Red, Green, 4-Color Variety Pack
- Buy Schmidt 888 Rollerball Refills 0.7 mm Medium Tip: Black, Blue, Red
- Buy Schmidt 888 Rollerball Refills 1.0 mm Broad Tip: Black, Blue, 6-Pack Blue & Black
Best for: Rollerball-style writing
Fit type: Possible spacer hack
Bottom line: Promising, but still not a guaranteed direct replacement.
Schmidt 5888 Rollerball Refill Hack
The Schmidt 5888 rollerball refill is another 111 mm rollerball refill to consider. It is similar in general refill category to the Schmidt 888, but the 5888 uses a metal body.
Like the Schmidt 888, the Schmidt 5888 is shorter than the 115 mm Lamy M63. That means it may need a spacer behind the refill to help it reach the correct position. This is not a guaranteed fit, but it may be a worthwhile experiment if you prefer Schmidt rollerball refills or want a metal-body refill option.
- Buy Schmidt 5888 Rollerball 0.6 mm Fine Point Refills: Black, Blue, Red, Green, 4-Color Pack
- Buy Schmidt 5888 Rollerball 0.7 mm Medium Point Refills: Black, Blue
- Buy Schmidt 5888 Rollerball 1.0 mm Broad Point Refills: Black, Blue
Best for: Metal-body rollerball refill experiments
Fit type: Possible spacer hack
Bottom line: Worth testing if you want a Schmidt rollerball alternative.
Common Spacer Methods for Lamy M63 Refill Alternatives
Most Lamy M63 refill alternatives need some kind of spacer. The spacer sits behind the refill and pushes it forward so the tip reaches the correct writing position.
Common spacer methods include:
- A small wad of paper
- A short piece of plastic tubing
- A spring from another pen
- A small plastic plug
- The rear plug from another refill
- Tape wrapped around a plug or shim
- A carefully trimmed piece from an empty refill
The goal is not just to fill empty space. The refill has to sit at the right depth, stay centered, and allow the pen to write comfortably. If the spacer is too short, the tip may not reach far enough. If the spacer is too long, the refill may press too hard into the nose cone or prevent the pen from closing properly.
Start with removable spacer materials before trying anything permanent. Avoid glue unless you are fully comfortable turning the experiment into a permanent modification.
What Can Go Wrong?
A Lamy M63 refill alternative may not work perfectly, even if another user had success with the same refill. Common issues include:
- The refill is too short.
- The tip does not extend far enough.
- The refill has too much tip wobble.
- The refill rattles inside the barrel.
- The pen feels scratchy or unstable.
- The cap does not close correctly.
- The spacer shifts over time.
- The refill works in one Lamy model but not another.
This is why fit is not guaranteed. The Lamy M63 refill alternatives in this article should be treated as experiments, not official replacements.
Lamy M63 vs Lamy M66: Do Not Confuse Them
The Lamy M63 rollerball refill and Lamy M66 rollerball refill are different refills.
The M63 is used in many capped Lamy rollerball pens. The M66 is a different rollerball refill used in specific Lamy models. They are not the same length, shape, or format, so you should not assume that an M63 alternative will also work as an M66 alternative.
If you are comparing Lamy rollerball refills, start by identifying which refill your pen currently uses. You can also review our Lamy Pens Guide for broader brand compatibility information.
Lamy M63 vs Pilot G2 vs EnerGel
The Lamy M63, Pilot G2, and Pentel EnerGel are all different refill types.
The Lamy M63 is a proprietary rollerball refill for capped Lamy rollerball pens. The Pilot G2 is a gel refill used in Pilot G2 pens and compatible gel pens. The Pentel EnerGel is another popular gel refill family known for smooth writing and quick-drying ink.
Pilot G2 and EnerGel refills may be useful as Lamy M63 refill alternatives only if you are willing to experiment with fit. They are not direct replacements.

Does a Schmidt 888 refill fit instead of a Lamy M63?
