• Like most of our cases it'll float if you drop it in the drink.
• The seams are high-frequency welded to form a super-strong bond.
• The Aquaclip® (a patented, ultra-secure, rustproof, injection-moulded plastic seal) opens and closes with a simple twist of two levers, and everything stays in one piece even when open.
