10 Pcs Blacklight Pen Set

Bought this to use in a homemade escape room. The pens worked great. Everything was visible under a weak black light. Good value.

Works very well When putting in a battery Light has a weight to it and Last very long The ink does not runs or smudge Dries very easy Stay on very long

Work great, I used them for a kids lesson at church and an escape room

Works as intended. The flashlights are a little flimsy feeling but works great for the money.

I bought theses for my kiddos, they love them. I recommend getting these. So much fun! So easy to use, quality is great! Love the design!

I ordered several of these to use with breakout boxes in my classroom. In each pack, I have one flashlight that not only doesn’t work but gets extremely hot—so I’m assuming it has some kind of short circuit. The other flashlights in each pack work fine. Regardless, when only some of the product works, it doesn’t make for as good a deal!

Perfect

I bought this set to make an indoor game for my grandkids. We looked up coloring page images and printed them out like oversized playing cards, then traced those images onto blank cards with the invisible ink. My grandson held the light so my granddaughter and I could see what we were tracing. We then hung up the invisible images around the house and mixed the other cards at ‘home base’. We had fun looking for the image in a race with the flashlights. This set was perfect, and they still play the game at their house.
