Exceeded expectations
Such a clever product. The UV light is bright enough to reveal the writing instantly. My kids have been writing secret messages all week. Will definitely buy more as gifts.

Great for creative games
We use this for scavenger hunts at home. Writing clues that only appear with the UV light adds such an exciting element to the game. Highly recommended for parents looking for screen-free fun.

Cute and functional
The pen writes smoothly and the invisible effect is magical for kids. It's a bit small for adult hands, but perfect for children. The cap clicks on securely so it won't leak in a pencil case.

Fun stationery item
Bought this for my niece's birthday. The build quality is good and the character design is adorable. The only reason I didn't give 5 stars is that the battery in the cap seems a bit dim after heavy use.

Genuine Sanrio quality
I was worried it might be a knock-off, but this is definitely genuine Sanrio stationery. The details on the My Melody figure are crisp, and the ink disappears completely until you shine the light.

Perfect gift for my daughter!
My daughter absolutely loves My Melody, and this pen is such a fun twist. The invisible ink works perfectly under the UV light cap. Great for leaving secret notes for her friends.
Q: Does the UV light work in daylight?
A: The UV light is visible in daylight, but the invisible ink is best revealed in low-light conditions or indoors for the clearest contrast.
Q: Is this suitable for left-handed writers?
A: Absolutely! The pen writes smoothly regardless of handedness, and the quick-drying invisible ink prevents smudging for left-handed users.
Q: Can I refill the ink once it runs out?
A: No, this specific My Melody model is not designed to be refilled. Once the ink is depleted, the pen should be recycled according to local regulations.
Q: Is the ink safe if it gets on skin?
A: Yes, the ink is non-toxic and safe for children. However, it is designed for paper use and should be washed off with soap and water if it contacts skin.
Q: Does the pen come with a replacement battery?
A: The pen comes with one pre-installed button cell battery. Replacement batteries are standard size and can be purchased at most electronics stores.
