Hi! My brother collects enamel pins and just bought his first geocoin, so I've been thinking about gifts for him that could combine both hobbies. Does anyone know if Groundspeak or its associates produce trackable enamel pins for hats, bags, etc.? I've been Googling for half an hour and all I can find are the non-trackable milestone and achievement pins. It would be nice to buy something premade instead of commissioning an expensive custom pin or engraving one myself.
(If these aren't a thing yet—Groundspeak, get on this! Enamel pins are hot right now, my brother alone would keep you in business!)
