Retro 51 Refills Easy-Flow 9000 Black Ballpoint Pen - REF71

Great replacement refill. Pen writes like new

Fits perfectly and works as advertised. Wonder value for the money

I really like this pen refill

Works for what I needed it to

Ink writes smooth. A must for those using the Retro pens.

just what I needed

I take complete responsibility but had thought I was ordering 1 refill cartridge of 3 items vs. 1 cartridge. But it will last long enough for me to reorder, so it is my bad.

This new cartridge skips and writes poorly, unlike others of this brand I've purchased. I can only conclude the ink is so old it is drying up. Look for a different seller.
