Attractive and really, a perfect size.
Color: Rustic Brown-2pack
They are a little larger than I thought, however, they will be perfect for what I need them for.
There not up yet, but I know that you will really love these! I do, and hopefully will have them up soon!

They serve the purpose
Color: White-4pack
These corner shelves are just what I wanted to hold our modem and router on one and a small lamp on the upper. The little ledge makes me feel confident that the devices won't easily be knocked off accidentally. My husband, a retired contractor, installed them so they are level.
They are made of pressed board with a laminate veneer of some sort. The laminate arrived damaged on one of the shelves, but I wanted to use two of them right away so a dab of paint will cover the damage if it's placed in an inconspicuous spot.
