Pilot Gel Ink Refills for FriXion Ball 3 & Slim 038 Pens, Extra Fine, Black/Blue/Red Ink, 3 Packs of 3 Refills Each

Write nice but quality is poor. Three of the refills broke within 2 weeks with the ball falling out of the writing tip, making it unusable. Also they don't last long, but guess that's down to the small size.

Best ink refills!!

The pen (body) can be used for a long time so extra ink refills are good.

They obviously work well but since they’re short, they have a tendency to run out quicker than your average pen…at least for me, I write a lot daily. Regardless, I’ve purchased them several times because they’re the best erasable pens I’ve been using for over 10 years

I tested one of each color as soon as I received them. They wrote beautifully - smooth and bright as the original. If only they weren't so expensive for the small amount of ink in each cartridge. The 0.38 size works well in my Hobo Weeks grid. I started using this Frixion ink because my Jetstream 3 refills always seem to fail. They were the most unreliable cartridge ever. They would clog up and refuse to start. I've thrown out 80% of my brand new refills because I couldn't get them to write properly. Anyway these refills work great out of the package.
