Review on Discreet Fun: GoPong Hidden Sunscreen Alcohol Flask - 2 Count by Theresa White

This product comes with small pads to close the hole so it doesn't leak. BUT they are for single use only and unless you drink a lot you won't drink the contents all at once and you can't reclose the lid to keep it airtight. I'll make it clear that it won't leak just standing on a shelf or something, but if any pressure is applied it will drip a little. I was able to reseal with plastic cling wrap, but if you're trying to pass it off as true sun protection, the piece of cling film sticking out the side of the lid is a sure sign.
