Lamy M66 Rollerball Refill

Lamy M66 Capless Refill

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
