Review on 🧙 Invisible SCStyle Birthday Halloween Christmas by Greg Greiner

I bought these to use as gift sets for my daughter's birthday party, among many other things. Most other stuff was great for fillers like plastic tight stuff, flex man, miniball and sticker sheets. But these took the cake. I don't know how long the batteries last but the kids had a blast writing down little secret messages and pictures and then secretly finding them under the black light. It was such a cool purchase at an affordable price.
