My Brother-in-law has the best Reef Flip-flops ever! Yes, that is a bottle opener on the bottom of them. How impressive is that??!! Imagine being at your beach hotel and you’ve just purchased a great six pack of delicious brew… and… you have no opener!! Never fear, put that bottle to the bottom of your Reef Flip-flops and pop that top – Flip-flop to the rescue! Ingenious! I totally need a pair of these!
