Scuba Diving Snorkeling Waterproof Cylindrical Dry Box with Clip

Inner diameter around 50mm/2inches, and about 120mm almost 5 inches long.I used this to store stuff for a recent shore diving trip. It easily fit car key fob, apartment key, and money. Drivers license or credit cards can fit but you need to flex/bend them a bit to squeeze them in. An extra mm would have been great but they do fit. Two cards might be the limit.It was completely waterproof on the dives, never a concern. I liked the lanyard and clip. I kept the canister in my BCD pocket and clipped it to a D ring. It might be a bit bulky to wear around your neck if snorkeling but should be doable and a better alternative then hiding your keys or leaving them on the beach. It would hold a variety of other things that you want to keep dry for any number of uses. .

Muy resistente al agua durante las inmersiones submarinas.

je pensais qui y en avais 3 pour se prix mes non 1 seul

You get one container. False advertising.

Water tight. Can carry car keys/fob and leave all other valuables locked in the car. Peace of mind.
