Cases slide out for ease of use, while they fasten shut so contents won't spill.  The cases have "grab" handles for ease of pulling out and carrying. The cart comes with rollers, but I chose not to use those as I did not want my cart rolling and that increased the height.  I keep the cart under a 6' table and it works perfectly.  One could also use the cart for photo storage too.The cases can be taken out of the chest and taken with the scrapbooker.

The only drawback I have found is that the cases will fall out if the cart is tipped forward ever so slightly.  It would be perfect if there were stops on the chest to prevent this.

I would definitely recommend purchase to any scrapbooker for easy organization!  I have three of the carts!
