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.

Highly recommend these shelves

Color: Black, Size: 2 Pack

Love these shelves! Easy to put up, stylish, well made and mounting hardware feels secure. Love the fine details of the included screws and anchors and small tabs to cover screws underneath.
