REUSABLE ICE MATS ARE A COOLER’S BEST FRIEND! Filled with water, these wafer-thin mats take up little room and stay frozen for hours! They’re flexible enough to wrap around bottles or odd-sized containers, or lay flat. Foods and beverages stay cold; no messy melting inside your cooler. Great for picnic baskets and lunch totes, too. Set of 3; each 16" x 8¼".
