The listing, NEW WOP Stackable Storage Containers has ended.
This is a set of stackable storage containers. They can be used separately or all hooked together. They don't hook sideways, just top and bottom. The drawers swing out sideways as in the picture. One of the drawers has a crack. I've tried to capture it in the photo so you can see it. It doesn't show unless you look close and it doesn't affect the functionality of the drawer at all. Each section measures 4-1/2" x 4-1/2" and is about 1-1/4" tall. There are 10 total containers - 8 black and 2 white.
