Query: Convenient but not 100% watertight, money got damp

Used this wallet on a recent 4-day cruise in the Caribbean while swimming and snorkeling. Very convenient to bring ID, credit card, and cash, however I didn't find it to be 100% waterproof despite the seal. I noticed that my paper money would be a little damp at the end of the day - but not completely soaked, and it wasn't as if the whole wallet had completely filled with water. Since everything else in there was a plastic card, and merchants are still willing to accept wet money, it wasn't a huge issue. For $6 I can't really complain anyway, worth the investment since it beats using a Ziploc bag because of the lanyard. Just wouldn't put anything in the wallet that absolutely cannot get wet.
