Most plastic storage boxes are made from a thinner clear plastic. As you can see from the pictures, these are slightly opaque, but mostly white, showing that it's a thicker and stronger material.
The lids can be locked into place with the blue handles for a very secure fitting. The box has plastic wheels on the base for easy movement around the house & office - even when it's full. The lid itself has indents in the same place as the wheels on the base, so the boxes can be stacked on top of each other securely without any problems with them rolling off.
