These trays are so easy to use. Just print a picture (or find one) that you like, cut it into a circle, glue into tray and seal glass dome on. The result is an impressive piece of jewelry that can be worn or given as a gift. I made several of these necklaces for a celebration of life for a friend who passed much too soon. I made keychains, too. They were a hit and her mother still wears hers often. I also made Christmas charms out of cards received the previous year, then presented them to the friends/ relatives that had given me the cards! This made a thoughtful and inexpensive gift! #Sponsored #RankBoosterReview #Yolyoo
