Abstract: A coaster for positioning on a surface within a refrigerator to provide a barrier between the refrigerator surface and consumables stored in the refrigerator can include an elongate panel having a first substantially straight side edge, and a second substantially straight side edge extending substantially parallel to the first straight side edge. First and second opposed contoured side edges connect the first and second straight side edges, and there is at least one perforated line, by which a portion of the panel is removable by tearing along the perforated line. As such, the size and shape of the panel can be varied to conform to a various shelves and bins within a refrigerator.
