ONLINE Colourful double-sided ink cartridges, red – green – black – purple, universal ink cartridges, compatible with all common fountain pens, even Lamy pens - Spare ink cartridges, 4-pack

I’ve been buying these for the last three years for use in my Parker. So regularly that I have a subscribe and save order. It’s the only pen I write with and I am writing for literally six hours a day. Just went on to order an extra pack as stocking up my bag before the Easter school holidays and saw it said on the product description’not suitable for Parker’. I reckon on my normal levels of at least one a week I’ve gone through just over 150 of these. The colour is rich (I’m not a purple person but it is part of my job requirement that I have to write in purple), I have never even had to flush out or wash my pen in that time (I know, this possibly makes me a bad pen mummy) - I just ‘pop’ and go!! Ignore what they say - theses cartridges are fab and work perfectly well in a Parker with no damage or leaks!!!

Fitted perfectly and worked a treat

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.

just ink but seems to work well. fitted perfectly, no leeks, writes well.

Works in Parker and standard pens, but not In Pilot pens. The ink itself is as you'd expect.

Good value at £2.49Wouldn't fit my Parker 45 properlybut ok in an old Mont Blanc penThe colour isn't really green it's more turquoise

These last a while, my son uses a fountain pen in school and the first cartridge has lasted several months.

Don’t know what it is about these cartridges but the ink flow and quality is poor at best. Using the standard, universal end and the fit is poor.
