Invisible Ink Pen Review by Michelle HAmpton

We used these at my daughter's 9th birthday party. The girls loved them. They were making mustaches and cat whiskers on their faces. They colored their finger and toe nails. Writing messages on their hands and legs was the obvious. Lots of giggles all evening long... (Posted on 5/18/13)

Nice Product Review by Derrick Jackson

The kids have really enjoyed the invisible ink markers. Trying to come up with other ways to use them. (Posted on 4/13/13)
