Nice brackets
These are nice sturdy brackets for butcher block shelf however they do bend a bit. We installed in a corner so was able to pin to side wall no problems on big shelf. The smaller shelf about 18” moves a bit up and down when loading. Now very little and no worries about it but not rock solid

Sturdy Shelf Brackets
I really like these shelf brackets. They seem very sturdy, which is great for my laundry room shelves over the washer & dryer pair. It's going to be great to FINALLY have shelves for laundry supplies or "buyers' club" household items like 12-packs of paper towels or 36-packs of T.P. I can hardly wait to have my sons install them so I can fill them up!

Perfect Nightstand Organizer and Looks Amazing
Color: Dark Brown
This valet tray is exactly what I was looking for. The wood looks great and feels sturdy, and it keeps all my everyday items in one place. I use it for my keys, wallet, watch, and phone, and my nightstand looks much neater now. Its great to keep all the thing you need when leaving the house in one place.
It’s the perfect size, well made, and looks nice enough to leave out on display. Would definitely recommend this if you want an easy way to keep your essential items organized or need a solid gift idea.
