Ahoy There! Decorate your beach or lake themed home starting at your doorway! Each mat is designed with colorfast fibers on a slip resistant rubber backing. This makes it easy to knock debris off your shoes when coming in and preventing a fall when the ground is wet. These mats are easy to clean as you simply shake the dirt out. Fibers will come loose as you begin to use the mat which is perfectly normal. Measurements: 30''W x .75''D x 18''H
