PPFISH Military Grade Air-Tight EDC Accessory Case, Pill Fob Capsule Keychain, Waterproof Match Case Battery Holder, Outdoor Survival Storage Metal Container Dry Box

This is a very nice high quality, container. The threads seal great and does exactly what you expect as keeps interior dry and safe due to its very durable construction, comes with extra O-rings (2) also. However, the measurements given are misleading as the 'inner diameter' top and bottom caps are not 27mm wide due to the threads and, in truth, neither is the body. The body itself is bit wider but not the top and bottom caps. My point here is the caps limit in length and diameter what you can store. I wanted to store my Apricorn secure USB drive, but I cannot. The true maximum internal storage is probably about 21mm (0.8-inch) diameter X 113mm (4.4-inch) Length.... These are not exact measurements so I would suggest 19mm (.75-inch) X 101.6mm (4-inch) to be safe. I will keep it as I think for the price vs. its quality I will most definitely find a use for it.

This is such a simple item that there is not really a lot to say about it. But the main things that I am looking for in something like this is that it really works as advertised. I can confirm that this container has been completely waterproof in my testing. It also seems to be very rugged. It's made from a good solid metal - it doesn't feel like it will crush like an aluminum can. Even the paint seems of good quality. I've had this a few months now and carry it everywhere and there is not a hint of the paint wearing anywhere. I find this to be an extremely useful tool for protecting small items.

It’s smell proof 100%, it’s solidly built, great seal and threads. Key ring for extra key is strong and in a pinch will break a window

Great item I personally use it for my nano ledger because I didn't want to pay an extra 10 bucks for the ledger case but just as good if not better...air tight n strong great item

I use these for a lot of things. Matches are dry when camping. My Ibuprofen or dry and not busted up. Definitely waterproof and I think they will last a lifetime
