Cute and functional
The cartoon characters on the barrel are very detailed and cute. My daughter uses it to highlight important dates on her calendar that only she can see. Highly recommend for students.

Good but needs a light
The pen itself is high quality, but I was disappointed that it didn't come with the UV light. I had to buy one separately to test it. Once I did, it worked perfectly.

Great novelty item
Works exactly as described. The gel flows smoothly and doesn't smudge. Just remember you need a blacklight to see what you wrote. My kids love using it for scavenger hunts.

Smooth writing experience
Unlike some novelty pens that skip or blob, this writes very smoothly. The disappearing effect is magical. Great gift idea for office pranks or secret messages.

So much fun for study groups!
I bought these for my study group to leave secret hints for each other in our notebooks. The ink is completely invisible until you shine a UV light on it. The cartoon design is adorable too!

Perfect for journaling
I use this to hide personal entries in my daily planner. It's a great way to keep things private while still having them written down. The grip is comfortable for long writing sessions.
Q: Can I use this on dark-colored paper?
A: Yes, the fluorescent ink glows brightly under UV light even on dark paper, making it ideal for creative projects on black cardstock.
Q: Does this pen come with a UV light included?
A: No, this package includes only the pen. A UV light source is required to view the invisible ink and must be purchased separately.
Q: Is the plastic body durable enough for a backpack?
A: Yes, the pen is made from impact-resistant plastic. However, we recommend using the clip to attach it to a notebook to prevent loss or damage inside a bag.
Q: Is the ink permanent or can it be washed off?
A: The ink is designed to be long-lasting on paper. While it is invisible to the naked eye, it is not water-soluble once dry, so please write carefully.
Q: How long does the ink last before drying out?
A: If the cap is secured tightly after every use, the ink can last for several months. Leaving the cap off for extended periods may cause the tip to dry.
