Perfect storage bin for Hot wheels.Planning on getting another pretty soon.Solid Quality material. It is double sided container. Nice sturdy handle to carry around. You might actually be able to stack 2 cars in certain slots. Keep in mind you may want to put cloth or something in between the cars to avoid paint chips or dinged up cars. Also each slot has a gap as well. They do move around a bit once you close the lid.I kinda feel the price is a tad bit up there wouldn't mind if was between $13-$20Probably more people would buy these bins if they were more affordable.All in all its a solid product. Would recommend to others.
