These are great drawers. They slide easily, but have catches that prevent them from falling out. (You can pull them out if you work at it, but the idea is that you fill the drawers in place.) They're not quite fully translucent, but clear enough that you can look in the front and see what's in a drawer. The units can stack on one another, too; I've stacked two or three freestanding sets pretty confidently, though I wouldn't go much beyond that without some other means to secure them to one another or to a wall behind.Overall, if you need a simple, consistent, and fairly sturdy way to store some small items or parts, these drawers work well.
