Nice shelves. Install was super easy except on one of the three shelves. The main mounting shelf holes were off so the shelf will not slip onto horizontal mounting poles unless I modify the shelf. So a 20 minute job becomes a two hour job. The mounting system does appear very sturdy just not aligned.

Beautiful Decorative and Light Weight Shelving!

Color: White

Beautiful shelving. Came with hardware for hanging and a ruler strip template for mounting locations, although the holes did not match up with the shelf holes. Shelves are just the right size for my purpose and also decorative and light weight.
