Review title: Secret Ink Pen Works Great
Product review: Some pens I saw similar to this have no light included. That's a nice feature, so you can see what you have written! It works well on every surface I tried, and it glows when the special light shines on it. The only minor problem I had was in writing without being able to see what I was doing. I suppose I could have turned on the light to do my numbering, but didn't think about that. I tried to mark on surfaces that wouldn't get a lot of wear.This product is a good idea. It's easy to use. I wish I had had one as a kid so I could write secret notes!
