I’m not normally the type to leave embittered reviews, but do not buy these shelves. They’re overpriced at whatever sale you might be seeing. Even installed and screwed tight they feel flimsy and jiggle around based on where weight is. 

I had SEVEN of the included drywall anchors simply snap apart or explode while I was installing these, leaving me to fish plastic bits out of my walls with a needle nose pliers. So while I did get the shelves installed, I’ve also done a lot of unnecessary damage to my drywall.
