Review on SCStyle Invisible Ink Pen Set Of 10 With UV Light - Magic Spy Marker For Kids' Secret Messages, Party Favors, Easter, Halloween, And Christmas Gifts by Bilal Cartwright

As soon as I purchased this and received it my son opened 5 pens and none of the lights worked even though the paper you have to pull was still in tact to prevent battery loss. Some were completely dead, one was almost dead with the faintest light and one worked for about 5 seconds and died. These must have been sitting around a long time because they were removed flagged as unavailable after my purchase. I want my money back!
