Perfect fit!
Color: Black, Color: Black
It is exactly what I needed. I love the expansion option and the toolbox that can be attached to the outside of the tray. I had a problem with the tray sliding after I adjusted to the size I wanted, but I secured everything in place with a few z-ties, and it works great. I also put anti-slip dots on the bottom, so it doesn't slide on the counter. I love it and I am very happy with my purchase!

We like it
Color: Black
It works well, holds everything we need it to, and the spout for draining water works well.
It allows us to be organised without a cluttered (or wet) counter.

Perfect, Versatile, Sink Organizer
Color: Black, Size: Medium
Perfect organizer for my kitchen sink.
Thoughtful design keeps water directed into the sink, not the counter.
Dividers can be moved to suit your needs. The hanging basket fits on either end, or sits in the top rack.
Holds a LOT of items beautifully!
