The ultimate key fob! When keys fall in the water, Key Buoy self-inflating key ring opens up, automatically inflating an air tube. Your keys rise to the surface, and the 14\" inflated tube extends above the water. Strong enough for items weighing up to 2.8 ounces such as keys, small tools, deck plate keys. Suitable for single use only, so keep a spare on hand.
