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

Great pens and love being able to buy just the refills. I wish they sold a 3 x 3 pack in just black, but regardless, nice to have refills for my less frequently used colors. I have found occasional issue of a new refill not writing (~1/8) but this is typically ones that are "older." They are 0.38 mm, as described. Ink color and strength are good for erasable, and they write smooth. I have been using these pens for years and the only time I've noticed loss of color was in direct sunlight for extended times (I.e. paper on dashboard of car for months).

I love these pens and love that they are refillable. Great quality and they erase cleanly. Works great for everything from notetaking in my Bible to writing on my planner.

love my erasable pens

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.

I found that the 0.38mm tips do not work well on a RocketBook. The slick paper keeps the ball from drawing ink, so you must prime it repeatedly on plain paper. If you're working with regular paper, you'll probably love these.

Fit right in my 3 color Frixion pen perfectly. Exactly the same as the originals.

Work great, and quick shipping

Best ink refills!!

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

Good price

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.

Great...super fine tip.

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