Holiday Floor Mat. Holiday Shells Floor Mat - This colorful floor mat measures about 18" x 30". The image shows a bucket overflowing with shells, star fish, and a sand dollar. It gives the image a great holiday feeling without being overwhelmingly "Christmas". There is pine fir decorating around the bucket with a red ribbon in the front. The backing is made from environment-friendly recycled rubber tires. Mildew and fade resistant. Clean gently with soap and warm water. Artist: Kathleen Parr McKenna. A MatMates product.
