The just over 2 inch in diameter Batman Symbol Button Magnet Bottle Opener is something Batman respects and probably has on his utility belt! I can think of all kinds of scenarios where one might need both a magnet and a bottle opener...mainly ones that involve going to the 'fridge, grabbing a frosty beverage and popping that top all in one seamless motion. You don't need to be trained by Liam Neeson to appreciate the Batman Symbol Button Magnet Bottle Opener that's for sure.
