Easy-to-grip, dog bone shape soaks up lots of water, holding it better than most sponges. Save time with the larger design, covering more area at once, that's perfect for both aiding in drying out the bilge, cooler or bait tank, yet narrow enough in the center to grip. Makes removing water left behind by bilge pumps or drains easier. 8 1/2"L x 4 3/4"W x 3"D.
