I Purchased several of the 5 & 3 compartment stax. I had recently purchased a nice jewelry armoire and needed to organize all my jewelry inside. When you get these, keep everyting! Do not throw anything away (well except the paper label stuff). I thought I was just purchasing the velveteen covered organizer trays but they each come in a clear heavy duty plastic tray with a thick piece of plastic that can be used as a cover. (Keep all of these as they will come in handy).  So I ended up with way more than I bargained for. If you try to stack the trays on top of each other they will stick together as they fit right over each other. put your stuff in one tray they put the plastic "cover" on top and then put the next tray on. It won't get stuck on the bottom tray. You can also put the top tray in the plastic tray and this will keep the trays from sticking together. I was very happy with these. I have a ton of jewelry and I needed a lot of trays that I could stack one top each other. They aren't cheap but I've looked around and if you can grab these on sale it's about the best price I've seen anywhere online.  Keep the tarnish sacks too and throw in the back of each drawer to help with any moisture.
