Review on 24-Pack Plastic Bead Sorting Trays - Diamond Rhinestone Plate Tray for Diamond Painting, Cross Stitch, Nail Art, Dotting Tool - DIY Art Craft Supplies, 3.8 x 2.1 inch (White) by Gelin Battle

Glad I bought them. Now I can lay out all those multicolored "diamond" puzzle pieces instead of fiddling with tiny plastic bags. If you shake the tray slightly from side to side, most of the pieces will slide into the gaps between the tabs on the bottom of the tray, leaving them (mostly) right side up and ready to use. It's much faster. A "grommet" on one end makes it easy to slip extra puzzle pieces back into their plastic bag. Update: I'm still happy with this product a few months later. I immediately ordered another set. I've marked mine with the most common symbols, so I can easily grab the right trays when setting up a new project. That'
