A sturdy holder
It’s made well and is versatile. I have the shelf as 2 separate pieces. Perhaps not meant to be separated, I have done so. The pipping pieces are mostly unfixed, so your options are greater as to your personal finish. I recommend greatly.

Great look and storage space
I've had these shelves for two years now, and still love them. I love the industrial style. They add lots of great storage space for a small apartment. I have two sets - one for the laundry room and the other as a linen closet. Assembly is okay. Make sure you follow the instructions.
