Sturdy & Perfect Size
Color: Black
Love this sponge/soap holder. This is a perfect size to put scrubs, sponges, brushes and soap. Keeps your sink area clean and organized. It’s very sturdy and drains right into your sink. It also stays in place.

Great find
Color: Black
I had something in my sink to hold my washcloth but didn't like how it took up sink space. This was the perfect answers and now I can hang my washcloth on this and it hangs just enough over the sink so the drips stay in the sink. Also enough room for my scrub brush and sponge. Very happy with this purchase.

Good design, but stainless color is more like chrome
Color: Stainless Steel
Quality is good and design is nice. Knocked it down one start because the stainless is actually chrome/shiny, not what we wanted but again works well and looks
