slightly annoying to hang
Color: Brown
A little annoying to hang but look great and seem to be holding up well! I have heavy plants on them and no issues at all!

Functional, Look Great
Color: Brown
These were nice corner shelves that were easy to install, and look great. There are plenty of other options on Amazon that offer more shelves and/or at a lower price, but these ones look nicer than most.
Overall they're pretty easy to install. It's not exactly a two-person job, but it is easier if you have help - someone to hold the shelf and a level, and the other to mark the holes. My only other recommendation is to check your L-brackets before you do anything. Some come bent inward, some bent outward. If they're really crooked it will make it hard to wedge the shelf into the corner and may result in uneven measurements/holes, so make sure you straighten them out first.

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.
