Good but fades quickly in summer

The pens work well, but during hot weather the ink disappears almost immediately after writing. Better suited for air-conditioned environments.

Excellent value for money

You get plenty of refills in the pack. They fit standard pens perfectly and the ink flow is smooth. Highly recommend for elementary students.

Great concept, works as advertised

I bought these for myself to improve my calligraphy. The fading feature is consistent, though it takes about an hour in cooler rooms. Overall very satisfied.

Eco-friendly and fun

Love that we aren't using tons of paper anymore. The grooved copybook combined with these magic pens makes learning to write actually enjoyable for my son.

Perfect for my daughter's handwriting practice

These refills are a game changer. My 7-year-old can practice her letters over and over without wasting paper. The ink fades just fast enough for her to try again.

No residue left behind

I was worried there might be ghosting on the page, but the trace-free claim is accurate. The page looks completely blank after the ink vanishes.

5 FAQ

Q: Are these refills compatible with standard ballpoint pens?

A: These refills are designed specifically for grooved copybook pens but will fit most standard pen barrels with a 0.5mm tip diameter.

Q: How long does it take for the ink to disappear completely?

A: Under normal room temperature conditions, the ink typically fades within 30 to 60 minutes. Higher temperatures may accelerate this process.

Q: What happens if the ink doesn't fade after a few hours?

A: If the ink persists, try exposing the page to mild warmth or sunlight, which activates the fading mechanism. Ensure the pen cap is sealed tightly when not in use.

Q: Can I use these refills on regular notebook paper?

A: While you can write on regular paper, the disappearing effect works best on the specialized grooved copybooks designed for this technology. On regular paper, faint traces may remain.

Q: Is the ink safe if a child accidentally touches it while wet?

A: Yes, our ink is made from non-toxic materials and is safe for children. However, we recommend washing hands after use as a general hygiene practice.
