These are WONDERFUL!!! I am so excited about these, I had a great idea one day, and looked and looked and searched and searched to find just what I needed to bring my idea to life......and these little Treasure Boxes do just that!! They come in two pieces, a front and a back and fit extremely tightly together....perfect to slip a favorite photo into and then use as a cabochon to bead around!! Or, add a treasure of your own.......some sparkling cubic zirconias (no larger than 2mm so that they fit) or perhaps some seed beads, a scrap of fabric from your wedding gown.....sand you brought back from your honeymoon in Hawaii.......the lock of hair from baby's first haircut, some small opals, flakes of Gold......fill with glitter, tiny shells, shark teeth.....the possibilities are endless!! And so fun, let your imagination soar!! Photos are examples of what you can do with these....no, you are not going to get the pics of my gorgeous daughter!! (or the cubic zirconias or opals for that matter, wink wink) We have these in two shapes and a total of 6 sizes; these are 54mm across.
