Kitchen organizer
Color: Black, Color: Black
5 star appearance, material, no assembly just place cup in the fitted area. ! Holds all my washing tools, dish detergent, rubber gloves n dish rag together; perfect. I thought it would be too small. Fits perfectly on the sink top.

Very functional
Color: Black
Love this so far! Perfect size and I like that I can extend it (or not) to make it fit the space. I haven’t had to use the drain part yet, but looks like it will work good!
