For artists who want their brushes to last, this mat offers air flow while drying as well as protection from damage. Sewn onto the bottom half of the mat is a sectioned brush holder made from 100% cotton cloth. There are 12 slots for brushes ranging from 2 in. to 5 in. wide. Just insert each brush handle into the sleeve and roll the mat up. The cloth will help keep from moving and being damaged while transporting from one place to another. Tie up with two strings.
