Nice sink caddy
Color: Gold, Color: Gold
It was exactly as described- looks nice on my counter. I haven’t bought the scrub brush I want yet to put in the taller space but it def dries fast anytime water gets on it. I like the look on my counter space. It’s not flimsy, I like the color of the gold.

Effective!!
Color: Black, Color: Black
This caddy keeps my sink organized. It absorbs the water when I place my sponges on it and its super easy to keep clean. I squeeze as much waster as I can from the sponges so it doesn't wear out. I've had this a little under a year and it has held up exceptionally well.

Perfect for beside any sink even dorms
Color: Black
I bought this for my son for his dorm room for his sponge for washing dishes and for him to put his dish soap and his hand soap for everything that he could keep it all tidy because he’s actually quite organized and he actually really liked it and it looked very neat. It’s easy to clean. It wasn’t too big everything fit perfectly for the Myers hand soap, and dish soap. The color is neutral almost masculine is gray and black. And there is no issue of it falling because he kept it on a side table away from the sink so that nobody else would use it so it would be just his. So It was altogether and kept everything organized. He really liked it.

Attractive and works great. Be sure to clean the suction cups and sink before using!
Style: Scroll
I have wanted a sponge holder to put inside my sink for a while now. I wanted something attactive and I wanted it to work as it should. Seemed reasonable until I started looking and reading reviews. The biggest complaint appeared to be that these sponge holders do not stay attached to the sink. The reviews for this particular holder were great. Customers stressed cleaning the suction cups and sink before using. I am really glad they did because holder arrived in the packaging with zero instructions. Because I read the reviews I knew what to do and it worked! I am very pleased with this sponge holder. It is attractive, it feels really sturdy and it stays on the side of stainless steel sink just fine.
