Good Quality for the Price
Size: 15.7", Color: Black
Surprisingly good quality for shelves made of particle board. They look nice and hold quite a bit of weight when installed properly. I ordered another shorter set of floating shelves from another seller on Amazon. Those shelves were of especially horrible quality when compared to these.
