cute and easy to install
Color: Brown, Size: 10.5" x 10.5", Set of 2
I needed a little shelf to put a plant in a corner and these were perfect. Super easy to install and worked fine even though it turns out my corners aren't perfectly square. Everything you need to hang the shelf is included. Once on the wall it is sturdy and doesn't wiggle. Perfect size for what I needed. The variation in the color makes it seem like higher end wood.

Cute shelf set!
Color: Brown, Color: Brown
Shelves look great in my room. Perfect amount of space to display my little travel trinkets. Super easy to install and seem to hold a good amount of weight as I have a Mason Jar full of sand/shells on one of them.
