This worked great on my IDs and cards but some of the money got wet. It fits our car key, but we had to switch to a dive box for better water protection. This works great to protect my ID and card as moisture doesn't damage them. It was a bit difficult to get the cards out of my sleeve. We opted for a touch credit card so I didn't have to take it out and it worked great. Just attach a carabiner with a lock or use a zip pouch and it will be great protection. I used the first one because it didn't fit in my swimsuit pocket, but it's more for women's bags than a product. I used it throughout my trip to Hawaii.
