Sturdy little bins - well, not little, more like mid/little sized bins great for anything really like screws or anything that you have tons of little pieces of. It took me looking back at the product listing to figure out how to stack them because the instruction sheet was a little small for me to read - yeah, my glasses aren't magnifying enough I guess. I do know that I'm going to get plenty of use of these bins in my shop - my wife and I tend to have tons of random screws all over the place - and having these bins will make organizing them so much better than just having them all over the place. I am glad they come in 2 colors, instead of just one continuous color, it helps break up the monotony of a single color, adds contrast. There were no defects in the plastic mold - no cracks or sharp edges - there were tons of pegs to connect the bins together. I still have plenty of bins left over - I created 4 stacks. I think the price of admission they are asking is fair, the build quality of the plastic is good, I don't think these are cheap, or flimsy.
