### ⭐⭐⭐⭐ Review
*by S***M on 24 April 2025*

These are very fun for the price. I got them for a treasure hunt puzzle game with a group of children. The lights aren't very bright, but I was pleased that I got several for the price (and I already have a UV flashlight so it wasn't a huge loss that they aren't the best). The markers were all full of ink--none were dry. They show up nicely under the lights, especially the pink. My biggest complaint is the blue appears to be pretty much identical to the yellow? At first I thought maybe there was a mistake and the blue marker got filled with yellow ink when they were made, but the blue pen is also the most visible pen under natural lighting, so it seems to be different. All of them are a bit visible until they dry, but if you look closely you can still sort of see the blue marks hours later. I may have gotten a bad one. The other pens are great though! I definitely recommend these (especially if others are getting better blue markers), they're lots of fun.
