Once it is put together and in place this is a handy storage box. It arrives flat. Four sides are attached to the base and fold up. The top snaps on and secures it all. It’s a fun bright yellow. There is a window on both of the long sides. You pull a little pin and the window folds open for easy entry. The clear smoky sides make it easy to see what’s inside. It is not a heavy duty container. I don’t want to move it a lot or the sides and top come apart.  However, it works great for setting on a shelf and keeping the dust off my tools.
