These pewter lapel pins and tie tacks are about 3/4 inch long. Choose serotonin (happiness), dopamine (love), or caffeine. Each is packaged in a recycled gift box and includes an informational tag about the molecule. Choose either the lapel pin style backing or a tie tack backing. Both are made of quality, lead-free pewter for MWM in by an artisan in New Mexico. (Caffeine and dopamine tie tacks are currently sold-out.)
