Lamy’s M66 is a rollerball refill designed for use with capless Lamy pens. You can a 3-pack of these for about $12.
This ink is sold in blue, black, red, and green. The blue ink is washable while the others are permanent.
The M66 is technically a proprietary cartridge but its shape and size are quite close to the of a European rollerball. This is why most Lamy rollerball pens can be used with Pilot G2 and Pentel LR refills with only a small shim in place.
The M66 is a proprietary refill shape designed for us exclusive with Lamy pens, including the:
- Lamy Swift
- Lamy Tipo
- Lamy Accent Rollerball
- Lamy Imporium Rollerball
- Lamy Logo Rollerball
- Lamy Persona Rollerball
