Good value pack
Ten refills last a long time. The only reason for 4 stars is that you have to wait for the ink to fully vanish before rewriting over it, or it gets a bit smudgy.

Smooth writing experience
Unlike other water-based pens that skip, these write consistently from start to finish. The grip fits well with the standard Liupintang pen holders.

Essential for groove books
If you own the magic groove copybooks, these are the only refills you should buy. They are specifically formulated to work with the grooves without bleeding.

Perfect for daily practice!
These refills are a game changer for my calligraphy practice. The ink flows smoothly and disappears just fast enough for me to retry the same character multiple times without wasting paper.

Great capacity, slight delay in fading
The jumbo capacity is real; I've been using one refill for two weeks. Sometimes the fading takes closer to 30 minutes in humid weather, but overall excellent value.

Kids love the magic effect
Bought these for my daughter's groove copybook. She is motivated to practice more because the writing magically disappears. No mess and very safe for children.
Q: How long does it take for the ink to disappear completely?
A: Under normal temperature and humidity conditions, the ink typically begins to fade after 10 minutes and disappears completely within 15 to 30 minutes.
Q: Is the ink toxic if a child accidentally ingests a small amount?
A: The ink is made from non-toxic, eco-friendly water-based materials. However, it is not meant for consumption. If ingestion occurs, please consult a medical professional immediately.
Q: Do these refills work on normal paper?
A: While they will write on normal paper, the auto-disappearing feature works best on the specialized surface of the Magic Groove Copybooks. On regular paper, the fading effect may be less consistent.
Q: Can these refills be used in regular ballpoint pens?
A: No, these are specially designed water-based refills with a specific tip size intended for Liupintang Magic Groove pen barrels. They may not fit or function correctly in standard ballpoint pens.
Q: What happens if I leave the cap off overnight?
A: Since this is water-based ink, leaving the cap off for an extended period may cause the tip to dry out. If this happens, try soaking the tip in warm water for a few minutes to restore flow.
