### ⭐⭐⭐⭐⭐ Pretty ink colour.
*by A***R on 12 April 2026*

These fit fine into a Lamy pen. The turquoise colour is very pretty, although quite light. Ink flows nicely and is good to write with.

### ⭐⭐⭐⭐⭐ Good replacement!
*by L***N on 8 May 2026*

Works great with Lamy fountain pen! The price is much cheaper! Will buy again!

### ⭐⭐⭐⭐ Will fit parker pens
*by C***R on 24 February 2025*

States that these inserts do not fit parker fountain pens but they do, however they do require a little bit of persuasion to do so. Just be carful as it can cause the Lamy adapted end to open and leak ink.
