Perfect for secret notes!
My kids absolutely love this pen. They use it to write secret messages in their diaries that only show up when they turn on the little UV light. The ink is truly invisible until exposed to the light, and the ballpoint tip works great for regular writing too.

Fun study tool
I bought this to highlight key points in my textbooks without making the pages look messy. It works well, though the UV light could be slightly brighter. Overall, a fun and functional stationery item.

Great quality for the price
The build quality is surprisingly good. The cap clicks on securely, and the UV light is bright enough to reveal the writing instantly. It's become a favorite toy for my nephew during our family game nights.

Battery died quickly
The concept is awesome and the ink works as advertised. However, the included battery only lasted about two weeks of moderate use. Make sure to have a replacement CR2032 battery ready.

Works exactly as described
No complaints here. The ink dries fast and doesn't smear. The UV light is small but effective. Just remember that sunlight can sometimes make faint traces visible, so keep your secrets indoors!

Amazing gift idea
Bought this as a stocking stuffer and it was a huge hit. The dual tip is very convenient, allowing for both highlighting and fine writing. The glow effect is magical and keeps children entertained for hours.
Q: Does the ballpoint tip write in normal ink?
A: Yes, one end is a standard blue or black ballpoint pen for regular writing, while the other end is the invisible fluorescent highlighter.
Q: Can I refill the ink once it runs out?
A: No, this specific model is designed as a disposable unit once the ink is depleted, but the battery is replaceable.
Q: Does the pen come with extra batteries?
A: Yes, the package includes one pre-installed battery and one spare replacement battery.
Q: How long does the UV light last on a single battery?
A: Under normal usage conditions, the UV LED light typically lasts for approximately 20 to 30 hours of continuous use.
Q: Is the ink safe if it gets on skin?
A: Yes, the ink is non-toxic and water-based. It washes off easily with soap and water.
