Great sink organizer
Color: Black, Size: 9.25″
Great sink organizer to keep things out of the way and tidy. Very easy to assembly and it comes with rubber feet to help prevent it from sliding around. It is very light though so if you dont have a heavy bottle to weigh it down, it can be easy to knock over.

Works!
Color: Black, Size: 9.25″
I'd been looking at this type of thing for almost a year. I thought it was probably one of those gadget things that never really work. I finally took a chance and so glad I did. This one works! It keeps my counter clean and water free. It's sturdy and I never worry about it tipping over.

Good Value
Color: Black, Size: 9.25″, Color: Black, Size: 9.25″
This sink caddy is really practical and helps keep the kitchen sink area organized. It holds sponges and brushes neatly, and the self-draining design works well to keep things from getting soggy. A simple but very useful addition to the kitchen.
