Love this sink organizer
This fits really well alongside our sink. Keeps the soap containers off the counter so the water drains off and keeps things much neater. When the tray is full, simply pour the water out, rinse, and put back.

Missing Dividers
Color: Black, Size: 9.4*4.1*5IN
Disappointed it was missing the adjustable dividers. Not great to hold dishwashing brushes. They slip right threw the side.
