Have a toast to fun with our 1.5" Flashing Beer Mug LED Blinkies! These flashing beer mug pins are perfect for Oktoberfest, 21st birthday parties, sporting events, or any other occasion where you want to enjoy a frosty mug or two-or at least the illusion of one! Each of our light-up beer mug blinkies features 10 LEDs, 8 yellow and 2 blue, so they'll last long past the last beer of the night. Use the butterfly connector on the back to attach your beer mug pins to almost anything. Please note the butterfly connector may create a small hole in the garment you attach it to. These light-up beer mug blinkies come with CR927 batteries included and installed and the batteries are replaceable. Our Flashing Beer Mug LED Blinkies are sold by the dozen and come individually packaged in a clamshell.
