Review on KITBEST [2 Pack] Car Trash Can: Portable Garbage Bin, Collapsible Pop Up Trash Bag for Car - Waterproof Trashcan, Waste Basket Bin, Rubbish Bin - Leather Car Organizer with Ample Storage for Garbage by David Romo

I love these! Best of all they are waterproof and if they get weird I can just wash them in the sink. I bought them on short notice for our first trip with two young children. Aside from being just awesome makeshift bins, I used one as a blueberry bowl and then just washed it in the sink along with the dishes. They fold up easily if you don't want to be pulled out all the time. They're not bulky, did I mention they're waterproof?! For example two waterproof layers. Highly recommended!
