Slide and stack compartments

These two little drawers I guess I don’t know what to call these, but you can stack things in them and as you take one out, it will slide the next one to the front they were used for make up. I have to wipe them down and get them clean, I’ve only use them with my make up and that’s it. One has a bigger slot in a medium slot and then small ones and then the other one has all the same size slot in it.
