Tegeme 10 Pcs Blacklight Pen Set 5 Invisible Ink Pen 5 Blacklight Flashlights, UV Pen Invisible Ink Marker Black Light Markers for Spy Secret Christmas Holiday Gift Party Favors

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.

The listing says both the battery is included AND that it’s not. Whatever, typos happen. It says it needs AA batteries, WRONG! The flashlights require AAA batteries and you pull the internal cartridge out to plug in the batteries.

If a child accidentally write on themselves, it will be very difficult to remove. Good thing you can't see it without a black light. For the price of the mini black light flashlights, it should come with batteries. The light wasn't bright, but very dangerous if kids point it their eyes. I don't recommend kids using this product, But if you insist, please use caution while doing activities with kids. Will not buy this item again. Hope my loss helps you.

As i said- it was much more then i expected!
