The big black piece in the front gets put in place when traveling so nothing accidentally opens and spills out. On the right side, it has a place where you can wrap your extension cord for easy transport. On the left side is where you store that same black piece when you're not traveling and are actually using it. It has two wheels on the back for easy moving.
When I flip the lid open I use the lid to hold stuff too. I get almost all my supplies off my work space with this handy little guy and I get more scrapping done too!
