Bought several pens for my grandchildren and 1 for myself, we have had a ball writing each other notes and i find that they spend more time doing cursive & printing with the invisible ink pen then they did with their regular pens. This is a must have for children who do not enjoy writing this will encourage them to write more often and is fun in the process.
I bought one for myself and my soon to be sister in law. I haven not used mine yet but her and her fiance have and said that it was great for their wedding rsvp's. This is great for when you need to keep track of something but don't want others to be aware of it. Comes with its own mini black light so its perfect
I ordered three pens for my nephews as a Christmas gift. Only one of the three pens actually worked so we will be returning them. The lights on two of the pens did not work. We also attempted to find replacement batteries but were unable to locate the specific type in any of our local stores.
horrible! don't buy this. I recently received 2 in the mail for my daughter and I but the light wouldn't work. it DID have batteries in it.
