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.
