Celebrate the humble vertebra with this cute lapel pin. Vertebrae are bones that stack atop each other to build the spine! Your backbone's 33 vertebrae work together to allow your body to bend and twist. Without vertebrae, vertebrates wouldn't have any protection for their awesome spinal cords, which make them extra-smart animals (or so they think).This marvelous little 1.25" printed aluminum pin comes packed on a card, designed in the USA and made in China.
