This is a simple but useful device that is indispensable for the art or craft studio. Made of very sturdy glossy plastic it has six indented wells that can be used for paint, glitter, beads, etc. The hard plastic surface will not absorb paint so it can easily be washed clean. Small enough to hold comfortably in your hand they measure 3-1/2" wide x 5-3/16" long and they have a little tab on the end so you can easily pick them up easily. The indents in the tray are approximately 3/8" deep. When not in use these trays can be nested so they take up very little space. You get 20 trays in this offer.
