Easy install shelving with heavy duty anchors
Color: Black, Size: 15.7"
Love this! The hardware includes heavy duty anchors, so this will allow objects that has some weight. The shelves can be arranged any way you like.

Very happy
Color: White, Size: 15.7", Color: White, Size: 15.7"
Easy to install, material could have been a little high quality but for the price I’m not complaining, the shelves themselves are very light weight and seem pretty durable but time will tell

Great corner unit - love the hole for wires!
Color: White-2pack
Perfect little shelf for our room! We wanted a small little shelf in the corner that could hold a charger and that hole cut out made it perfect for our needs! I really liked the style of it and the little bar around the front. Sometimes cups or something get put on it and this stops them from falling! These shelves feel super sturdy and took me 2 minutes to install!
