Perfect for my third grader!
My daughter loves these refills. The colors are vibrant, and the erasing feature works like a charm without tearing the paper. Great value for a bulk pack.

Works as expected
The heat erasure works well with a standard eraser on the pen cap. Ink color is consistent. Would buy again when we run out.

Good quality, smooth writing
The ink flows very smoothly. I bought these for my own note-taking. The only reason for 4 stars is that the black runs out slightly faster than the blue ones.

Teacher approved!
I bought these for my entire classroom. Students make fewer mistakes because they can easily erase them. The 3.4mm core fits all our standard pens perfectly.

No more messy correction fluid
These refills have saved us from buying correction tape. The ink disappears cleanly when rubbed, leaving no ghost marks. Very satisfied.

Excellent bulk deal
You get so many refills in this pack. The crystal blue is a unique and pretty shade. Highly recommend for anyone who goes through ink quickly.
Q: Can the ink be erased after a long time, or does it set permanently?
A: The heat-sensitive ink remains erasable indefinitely. You can rub the text to erase it even weeks after writing, provided you use enough friction to generate heat.
Q: Are these refills safe for young children to use?
A: Absolutely. The ink is non-toxic and acid-free, making it safe for Grade 3 students and older. Always supervise younger children during use.
Q: Do these refills fit Pilot FriXion pens?
A: Yes, the 3.4mm universal core is designed to be compatible with most major brands of erasable gel pens, including Pilot FriXion models.
Q: Is the 'Crystal Blue' significantly lighter than 'Ink Blue'?
A: Yes, Crystal Blue is a lighter, sky-blue shade, while Ink Blue is a deeper, traditional navy tone. Both are clearly visible on white paper.
Q: How many refills are included in the bulk pack?
A: This specific bulk pack contains a total of 50 cartridges, mixed across the three available colors: Crystal Blue, Ink Blue, and Black.
