DirectGlow 3pc Invisible Ink Pen Marker UV LED Flashlight Black Light Reactive Blue Red Yellow

I loved these!! Used these to make a poster for a gender reveal party for my daughter to announce our granddaughter!! We brought a black light so it was easy to see ITS A GIRL!!!

I love this product I use it on occasion. I write a little note to my kids or girls lol.

I liked the marker's but one was almost dried up after a few uses. The other two aren't far behind. They must have been around a long time or used, I don't know. Won't buy again.

The blacklight was missing in my package. Luckily I already had a blacklight flashlight, so it wasn't a big deal. However, the markers work well and dries without leaving any traces of visible ink. The ink is very bright under blacklight so overall I am satisfied with this purchase.

Got this to host a glow in the dark party for my kiddos… they loved the activity, a must buy!

I used these to # the backs of my RSVP's on my wedding invitations. Quick Dry and within a few seconds, I couldn't see it at all. Ok, so using the light was cool. I will give the rest to my niece & nephew!!

The markers are good but the light broke after a few days

My grandkids love using these pens for lots of things. They like writing "invisible" clues on paper and then using the lights to reveal clues, sending each other (and sometimes grandma) on treasure hunts around the house. They are also fun to use for other activities. I am glad I purchased these.

I rated this product three stars for the three markers that I got. There was no light. The markers are fine but without the light it makes them useless.
