Review on 📦 Madesmart 8-Piece Interlocking Bin Pack-Carbon Collection: Ultimate Customizable Storage Solution, Durable, Easy to Clean & BPA-Free by Arlene Byrd

These trays are about what you would expect for $10. They are made of black plastic of reasonable strength and I have no doubt they will last a long time in a desk drawer. They are great for storing smaller items as well as larger items like pens, pencils and keys that have been rolling around on my desk. The only complaint I have is that they are difficult to block in different configurations. There are no instructions on how to do this, but with a little effort you can arrange them in different positions. The only trick is that they don't mesh neatly. Some of the containers don't seem to want to snap into others at all. I kind of squeezed them, but it wasn't smooth.
