Pilot FriXion Ball Refills for 3 Gel Ink Multi Pen & Slim 038 Pen, 0.38mm, Black/Blue/Red Ink, 3 Packs (9 refills)

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.

It was a perfect fit for my frixion pen.

Love this pens. I make so many mistakes (and bad handwriting) so the pens are perfect to use for this. Easy to refill the pens, color is bright and dark. Shipping was great and on time, packaging was good too

Awesome to not have to buy pens instead get the ink. Sometimes the ink is old in them.

Work great

I love the super fine tip of these and the smooth writing. No clots or leaks. What I love most is the ability to erase any mistake with ease and rewriting over it without trouble. It lifts of the page without residue and allows me to write in the same area with same fluidity as before. I always keep the refills handy as I use this pen A LOT

I prefer a fine pen to keep notes and update my scheduler. These are fabulous. The colors are true and the fine tip is wonderful. I also appreciate that the pen is streamline and does not have a 'fat' barrel. Unfortunately that means that there is less ink. This is a small inconvenience for the quality of the pen. Having it as erasable is a bonus - no white out in my scheduler. I've bought them several times and will continue to do so as long as they are available.
