The material looks very delicate, breakable easily.great box.....Easy to install..........Only mine didnt come with instructions..........Here's the reason why i only gave the VOWAGH truck bed storage toolbox left and right side a 4 star.No installation instructions, poor packaging and not the same key for both boxes. They also stick out past the finder wells in the truck bed.One box lid had some small damage to it but still works fine. Without installation instructions this made it take a lot longer to mount the doxes. And instead of having one key for both tool doxes, you have two keys.Junk
