Ignore the “Frequently returned item” message!
Color: Walnut Color, Color: Walnut Color
I usually don’t write reviews but I thought I should for these shelves. I was a little skeptical on these based on the “Frequently returned item” message but I decided to give them a shot and I’m glad I did! These shelves are solid and well made, beautiful color, fit perfectly in the corner of my wall, and are easy to hang. I’m not sure why they are frequently returned but I will be ordering another set for my wife’s side of the room.

Good looking, quality control needs improvement
Color: Acacia
The shelves are fine but one of the mounting blocks was glued on backwards which meant the holes for countersinking the mounting screwed ended up on the wrong side. It was easy to drill new countersinks so no big deal but a star is docked for quality control. They are cheap and looks good so I can't complain much.
