I have many sets of these and adore them. I keep 3 stacks on my worktable. The top tray in each is for small embellies like snaps, brads,primas, buttons etc. I was having an awful time with my brads and clips sliding under the deviders and getting all mixed up. I tried lining the bottom with felt. It didn't stop the sliding and made the lid not fit. I tried foam, same thing. Well I was making cupcakes with the 4 year old and it hit me - I have lined each section with a silver foil cupcake wrapper. It works PERFECTLY. I have a photo-a little shiny but I'll add it anyway :)
