Gel Gems look like jello but that's where the resemblence ends. Gel Jams are window clings that are best used on glass surfaces including but not limited to windows, drinking glasses and shower doors. These decorative whatnots can be used to leave a note for your sweetie or create a pretty design for anyone to see (maybe a Happy Holloween message to Trick or Treaters). Gel Jams come in many different shapes and colors...and the latest gems light up! Here are some of the decorations made with these products. Just think of all the possibilities!
