Lamy M63 Green Refill: Choosing the Right Replacement

By: Joybuy Product Recommendation OfficerDate: 2026-07-17

A Lamy rollerball pen offers a consistently smooth writing experience, but even the best ink eventually runs out. If you're specifically looking for a Lamy M63 refill in green, you want to ensure you find the correct product for your writing instrument. This article serves as a practical guide to help you identify the right replacement refill and verify compatibility with your pen model. We'll clarify the key differences between refill types and present a selection of suitable products.

What to Look for When Buying a Lamy Replacement Refill

Choosing the right refill is straightforward once you know the key criteria. Consider the following points to make an informed decision.

1. Compatibility: M63 or M66?

The most common reason for an incorrect purchase is confusing the refill types. Lamy offers two primary systems for its rollerball pens, which are not interchangeable:

• Lamy M63 Refill: This refill is designed for Lamy rollerball pens with a cap. This includes popular models like the Lamy Safari, Lamy AL-Star, Studio, Logo, Pur, Accent, and Vista. If your pen has a separate cap to protect the tip, you need an M63 refill.
• Lamy M66 Refill: This refill was developed specifically for Lamy's capless (retractable) rollerball pens. Models like the Lamy Swift or Tipo use this system. The Lamy M66 green is engineered to resist drying out quickly when the tip is extended.

Therefore, before buying, check whether your Lamy rollerball pen has a cap. This is the decisive factor in choosing between the M63 and M66.

2. Line Width and Color

The designation Lamy M63 Medium (M) indicates the line width. Medium is a standard width suitable for most everyday writing tasks, from taking notes in class to signing documents at the office. The green ink offers a welcome change from classic blue or black and is excellent for structuring text, color-coding highlights, or for creative projects like bullet journaling.

3. Original Quality for Consistent Performance

Using genuine Lamy replacement refills ensures that the fit, ink flow, and writing performance meet the manufacturer's specifications. The metal casings of the refills are durable, and the ink flow is calibrated for Lamy's writing systems, promoting a clean and consistent script. When you buy a Lamy refill, the original is a reliable choice.
