Query: Would not trust with important stuff

Recently purchased for a trip to the Cayman Islands. Haven't had a chance to actually use the pouch but the sealing mechanism seems sketchy at best. It consists of double-folding the top of the bag and sealing it with velcro, yes velcro.I tested the pouch by putting some paper in it and left in a tub of water for a few hours while also occasionally bending/folding and agitating the bag to simulate real world snorkeling/diving conditions. After removal the inside of the bag was slightly damp and had let in more than just a few droplets of water, but not much more. Still good for keeping most things relatively dry but if its anything important/electronic, i would not trust it in this pouch.
