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.
