Don't know the name of the container but it looked like this: CONTAINER. Single o-ring but looked pretty sturdy. Top screws into the bottom.What is commercial name of container? How many O-rings? Were you worried about its waterproofness?
Funny you should ask about waterproofness. My girlfriend had one of these - CONTAINER #2 - and suggested we use it because it was smaller. But I wasn't too nuts about the integrity o-ring - we used to sell them and I don't recall them being too sturdy - so I decided I'd do a test dive with it. I put some toilet paper inside so we'd be able to tell if ANY water got it, sealed it, and dove. Opened it up at the end of the dive . . . and it was TOTALLY full of water. Glad I didn't have the key in there.
