Fun toy

### ⭐⭐⭐⭐ Fun colors, worked well for at-home escape room!
*by M***E on May 4, 2026*

I would rate the pens themselves 5 stars! They work great, and I love the color variety. The blue and yellow markers show up similarly under UV light, but the pink is super bright! I used these pens for an element in my at-home escape room, and they were definitely a hit. My only complaint is that, of the 6 UV keychain flashlights I received, 2 were very difficult to toggle on. For one of them you just had to push very hard, the other I never got to work. That said, for the price and the color variety, I would absolutely recommend these pens!
