Perfect, sturdy/ stable, great for the price. So easy to hang. So far very stable and holding a decent amount of weight. Perfect for my sons room and all his legos to keep out of baby brothers reach.

Very sturdy and all hardware needed
Size: 9.25”, Color: black-12 pack
These brackets are very sturdy and came with all the hardware needed, including two types of wall anchors if you won’t be going through a stud, and a magnetic level which was very useful. Would recommend.

Great Tray For Storing My Everyday Carries
Size: 8.5" x 5.8" x 1.9", Color: Black
My everyday carry items (wallet, keys, etc.), used to just get thrown around wherever when I'd get home, but this little tray makes a great, defined, space for me to keep those things when I don't need them on me. The soft lining reduces the obnoxious sound of throwing keys on a hard surface, and of course keeps me from scratching up a surface. The build feels quality and I haven't seen any damage to it yet. Also the all black version with gold buckle looks quite good and adds a subtle touch of luxury. Absolute recommend for the price.
