It's exactly what it advertises and does everything I need it to. Enough space to fit my phone, readers, car keys, AirPods, wallet, and a little extra space for a small candle. I only wish the slot for the charging cable was a bit smaller sometimes the charging cable will slide out since there is nothing to catch it or secure it in place.

Excellent Quality and Worth Every Penny!

Size: 11.25“, Color: black-6 pack

I recently purchased the LEOPO 12-inch Shelf Brackets, Thick Heavy Duty Industrial Brackets, and I couldn’t be more impressed. The craftsmanship is exceptional—solid, well-constructed, and clearly designed with attention to detail. Installation was quick and effortless, and the brackets held perfectly level and secure right from the start. They feel incredibly sturdy once mounted, providing reliable support and excellent stability for heavier shelving loads. The overall durability and performance exceeded my expectations, especially for the price. I’d highly recommend these shelf brackets to anyone looking for strong, stylish, and dependable hardware to upgrade their storage or décor setup.

Perfect

Size: 9.25”, Color: black-4 pack, Size: 9.25”, Color: black-4 pack

very nice brackets..very sturdy. Fits a 1x10 board perfect. Comes with everything you need and a.cool little level also. I loved them.so much I bought another pack and decided to add more shelves for my plants. It was easier to mount the shelf to the bracket then mount the whole shelf. Holds almost all my plants some are pretty heavy.
