Perfect for my daughter's handwriting practice
These refills are a lifesaver! My daughter can practice her letters over and over without wasting paper. The ink fades just fast enough to let her try again.

Teacher approved!
I bought these for my classroom. The kids love being able to erase their mistakes naturally. Highly recommend for early learners.

Great eco-friendly option
Reduces paper waste significantly. The ink quality is good, though sometimes the fading leaves a very faint shadow, which is actually helpful to see progress.

Decent but not magic
It works as described, but don't expect it to vanish instantly. It takes about an hour. Still useful for saving on copybook costs though.

Good value but fades quickly
Great product overall. The only downside is that the ink disappears a bit faster than expected in hot weather, but still good for daily drills.

Fits perfectly in groove pens
I was worried these wouldn't fit our specific brand of groove pens, but they slide right in. The writing flow is smooth and consistent.
Q: Can I use these refills on regular paper?
A: Yes, you can use them on regular paper, but the disappearing effect works best on the specialized coating found in practice copybooks.
Q: Is the ink safe if a child accidentally ingests a small amount?
A: The ink is made from non-toxic materials safe for children's use, but it is not intended for consumption. Please consult a doctor if ingestion occurs.
Q: What happens if the ink doesn't fade?
A: Fading speed depends on temperature and humidity. If it doesn't fade, try placing the paper in a warmer environment or ensure you are using genuine refills.
Q: Do these refills work with standard ballpoint pens?
A: No, these are specifically designed for auto-disappearing groove practice pens and may not fit or function correctly in standard ballpoint pens.
Q: How long does it take for the ink to completely disappear?
A: Under normal room temperature conditions, the ink typically begins to fade after 10 minutes and disappears completely within 30 to 60 minutes.
