Bar shelf liners often rest on back bar shelves, unnoticed and under appreciated. These non-stick heroes cling to shelves and keep bar glasses and bottles from slipping and sliding on a smooth shelf surface by providing a sticky, rubbery resting place. Most shelf liners come in a roll, just like wrapping paper. You simply unroll the amount you need, cut off a sheet with scissors, and trim the liner to fit your shelves. Shelf liners are thin and unobtrusive, adding a non-slip surface to your smooth and slick shelf surfaces. These shelf liners also make storing bar glasses and other wares more hygienic, allowing the rims to be kept slightly above the shelf surface and off any spills or standing water.
