Perfect for your sink organization
Color: Silver Grey
I have searched many sites for a product that will fit on our sink for all our kitchen and dishwashing needs and I finally found this product which proper fits with our kitchen decor and fits perfectly on our sink and it is very strong. I’m not worried about it breaking it anyway. Well with the price.

Love it
Color: Mattle Black
We'd been looking for a sponge holder we liked for a while andy wife came across this one. We were not disappointed. It's plenty big to hold a handful of sponges and scrubbers, plus our hand soap. I like the design that lets excess water drip back into the sink. Looks pretty low profile and sleek too
