Now that I have used 2 different sizes of the product inside my work van, I want to say that this is 'perfect'.  I am a bit difficult to please, but this product is great.  The material is neither too soft nor too hard, do not open by themselves, are easily to remove when you want to refill drawers, stack tightly and easily, fit in a variety of places, are not as noisy as metal (with no sharp edges), you can see what's inside, and best of all, BEST OF ALL, they are still working after almost 2 years!  Am I still living in America?  TJS
