I needed a slimmer sponge caddy, that could still hold my bottle brushes & extra sponges because my sink ledge isn't that wide... The rest of the ones I found were about 5 in, I needed this one that was only 3 in deep... Pitch perfectly and holds quite a bit. It's so worth it even if it rusts I'll buy another one! It looks great, study, drains water good, and the height is enough to hold my bottle brushes without them falling over. Does exactly what it's supposed to 😘
