Go big
Color: Black
I had a very small holder that barely held anything, the I stumbled on this in the small size, which I almost bought because it was a little bigger than what I had. Then I saw this one and I'm glad I bought the larger one because it holds everything! I even bought a glass container for the dish soap. Fits perfectly in the space. I also like the idea of the stone to absorb water instead of it dripping in a tray that runs through a spout into the sink.

Everything works great!. The item lets water drain easily. The brush holder and sponge holder pieces fit together perfectly in place. The item sits on my sink with no issues and has so much space for all of my sponges,brushes,and soaps. Very durable and sturdy, I even hang my kitchen cloves on the small rag holder. I love the Design!
