The ultimate key fob for boaters!
If your keys fall in the water, the Key Buoy opens up like a clam and, within 60 seconds, a water-activated chemical reaction inflates a 14" long, bright orange, tube-shaped float which rises to the surface and sticks up out of the water, with your keys still attached.
The Key Buoy maintains buoyancy on the surface of the water for about 40 minutes.

The activator is sodium bicarbonate and tartaric acid, a mild irritant avoid contact with eyes and skin.
