I have the dirty bird brush scuttle. It was not working for me....once my bush was loaded with water and lather...my brush did not fit far enough down to keep it warm, plus lather sank to the bottom and my brush could not pick it back up.

The other day in the store I saw a Koziol Latte cup in the store ( I live in the middle east) so I picked one up and came home.
Seemed to be able to hold my 26 mm knot with no problem

Then I pull out my older huge cappuccino mug from a thrift store back in the States, And now I have a way to keep my bigger brushes warm after I face lather.
