The Shaker Mat™ was designed with working bartenders in mind. This mat gives them extra drain room for cocktail shakers to keep bar tops spill-free and sanitary. Don't use dirty towels on your bar or take up space with a server mat for mixing. This Shaker-Mat™ measures 9" x 4.375" and is available in blue, red, green, and black. They're large enough for single bartenders but small enough to be coupled together for multiple applications.
