It's a Clear Plastic Storage Bin, we use the Sterilite kind. I think it is about 2-1/2' x 1-1/2'. We like the kind that have the snaps or latches to close them securely.
We store extras in it like my make up mirror, blow dryer, extension cords, batteries, etc. The sides are sturdy. I also have one that I put my snacks, extra cups, plates, napkins, etc. They work really well, as once at the WL we had one of the bell service guys drop it off of the cart. He was trying to balance it on the top of the suitcases, why, I don't know. But nothing broke.

We keep it packed and just throw it in the truck when traveling.
We went to a craft store and got all sorts of Disney, Epcot (countries) and Food & Wine type stickers and decorated them!! So much fun.
We've been asked several times if we are a professional packing company or if we had this done professionally.
I will try and get a photo posted.
