shelves were as stated . easy to put together .i used a rubber mallet. large enough to hold most size bins. seem strong. look great!!!! i was so happy to find these . way cheaper then building wooden ones and can be moved unlike wood shelves . i am so happy that i can go down to my basement and see everything all neat and tidy . no more digging around for stuff. i got seven of them no regrets. thanks wayfair......
