There is a set of these "pearls" at Michaels which piqued my curiosity, but were priced a little too high for me (like most scrapbooking toys). I found some single bottles and decided to splurge on one.
This one works way better than the 3D paint I bought at the dollar store. This one does seem to hold its shape much better (though it does shrink a bit after drying). It takes sooo long to dry, that even after 8 hours the tops got a little dented after closing my journal page.
