They both float just the same. And they both carry the same guarantee.

Who is it for?
If your phone goes anywhere near water, this case is for you.
From the cork oak to your pocket
Cork oak
High density and natural buoyancy: cork floats on its own, no tricks.
CNC cutting
Every model with its exact geometry: buttons, camera and port always clear.
Laser engraving
The designs are engraved into the cork, not printed or stuck on.
Multi-layer paint
Finished layer by layer and checked piece by piece before it leaves the workshop.
Made in Spain by us. No middlemen.
If it doesn’t float, you get your money back.
No odd conditions and no small print.

Questions before you buy
Yes, 100%. Cork is less dense than water: your phone in the case stays on the surface and you get it back. And if it doesn't float, we refund you.
The case isn't waterproof: it's made for phones rated IP68 or higher, which already resist water. Its job is to make it float so you can get it back.
It's a flotation device, not a diving one: we don't recommend it below 3 metres. If your phone isn't water-resistant, the case gives it buoyancy and shock protection, but it won't stop water getting in.
Both float the same. Slim if you want the smallest and lightest one with the same safety; Extreme if you want maximum protection for tougher use.
Classic finish: order before 13:00 (Mon–Fri) and it ships today, reaching you in 24 h in mainland Spain. Engraved designs: made to order for you, between 2 and 5 working days.
