Review: Wonderful, fun gift for kids - We put these and a little notebook in the stockings of kids at a family party and they were a HUGE hit. Kids of lots of ages LOVED being able to draw and write with their pen and then use the light on the back to see their secret design. The quality seems good, they were easy to use and held up to some "exuberant" use from younger kids. We were really pleased with these.
Review: Durable and great little classroom gift - I purchased these pens for my kids birthday so he could pass them out to his class mates. The kids really enjoyed them and the durability of them is great. We had 1 pen light break but that was the only issue we had.
