Available in clear or black, these interlocking shelf mats are an economic and ideal way to store you bar glassware. Each section measures 12 x 8 and have interlocking features on both the long and short sides of the mat, allowing you to expand its size in either direction to fit your glassware storage area. They are constructed from a flexible plastic material that will keep the rims of your glassware steady and lifted from surfaces that tend to accumulate bacteria. This sanitary solution is available in packages of 10 or by the case of 150 at desirably low prices.
