Floats up to 60g of keys or your phone when it's inside a SwimCell Waterproof Case. It will also float a GoPro and other action cameras. This is 33% more than a cork float!
It's the perfect companion to a SwimCell if you want your phone to float or if you think your keys might go overboard.
For electronic car keys always put them in a SwimCell waterproof case first and make sure to check out our silicone key covers too.
