## Customer Reviews

### ⭐⭐⭐⭐⭐ Absolutely fantastic.
*by J***E on 11 June 2025*

When you have multiple fountain pens, cartridges become hard to get for some. This brand of cartridge is 100% brilliant. Can recommend over and over !

### ⭐⭐⭐⭐⭐ Works Great
*by M***D on 12 January 2025*

Fitted perfectly and worked a treat

### ⭐⭐⭐⭐ 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.
