No, we're not talking about Aunt Pauline. We're talking about that heart in your throat moment when you drop the car keys over the side of your new boat! Fear not, if your key is attached to a Gemini Keytainer or floating Foam Key Tag. Foam Key Tags are made from 3/4" thick coated foam and are available in 5 colors. Each comes assembled with a 4" steel chain. Keytainers are made from a tough water resistant flexible vinyl that will float and save you from the sleeping with the dog. Each comes assembled with a 4.5" aluminum chain.
