Great item!

These shelves were great! I put them in the bathroom and helped with added space for holding candle and items to help keep counter clear.

Good quality
Color: Dark Walnut, Size: 11.2inch(2PCS)
These were the perfect fit, and they came with all the necessary hardware. We like them so much that we bought a different size for another room in our house, and they were perfect as well. They are a very nice quality wood. It's not that cheap stuff that will fall apart.
