I purchased these so that my kids could put their phones in them while at the beach. We go to the beach in the summer quite a bit because it is close to our house, and I am always concerned that someone is going to forget to take their phone out of their pocket, and that the phone is going to get destroyed due to water damage. Before we ever took them out to the beach though, I tested them by putting paper towel inside and submerging them for about half an hour. When the paper towel came out dry, I figured we were pretty safe. Since then we have taken them to the beach and had no issues with moisture. My kids like that they can still use their phone with this case on, and I like that no one is going to end up with a waterlogged phone that can’t function.
