As seen on Dragon's Den

Dropping your keys into the river, lake or sea is all too easy (besides expensive, inconvenient and embarrassing), but traditional floating key rings are bulky and will only support a couple of keys. The Waterbuoy Floating Keyring is an amazing new version just 3” long – an easy fit-in-your-pocket or bunghole – yet has the ability to bring loads of up to 2-lb (1kg) back to the surface.  And if you get a dry pod too then you can look after your phone, credit card and carkeys!    

There's a small gas cylinder inside the smooth, soft-touch Waterbuoy's floating keyring casing that inflates a puncture-resistant balloon after submersion (it has undergone plenty of splashtests so we know it doesn't go off early). Uniquely, inside the balloon is an LED light, visible at 850ft and lasting 24hrs – the Waterbuoy is the world’s first floating key ring that you can see at night.
