Keep your valuables afloat with our Floating Marsupial Keychain and Wallet. The zip pocket keeps ID, credit cards, or cash secure and a slide pocket hides your keys when not in use. Floats up to 2.6 oz (75g) - about 5 keys.
This thing is so useful. It floats on the water, but it is not waterproof. i can carry a lot of cards inside and not worry about it sinking away. a life saver. only complaint is it's not big enough for people with more cards
