Great organizer for your kitchen sink
Color: Black
Wonderful for our kitchen sink. It holds exactly what we need. Just wish it was a little bigger. Other than that, it looks fantastic and keeps what we need close by.

Sturdy and practical
Color: Black, Color: Black
Doesn’t take up a lot of space. The basket to hold your brushes can come out. So if you have a shorter brush you can use it without the taller basket. Holds my hand soap and dish soap with extra room if needed. Has a little shelf on the front that I put my straw cleaning brush. The bottom dish comes out for easy cleaning and catching water drips. It’s sturdy and pretty cute.
