What is an Eco Enamel Pin? Eco enamel pins are our conscious response to the environmental impact of traditional enamel pin manufacturing. Recognising the harm caused by the industry—both through its production processes and the carbon emissions from importing pins via air and sea—we took matters into our own hands. Our eco-enamel pins are crafted right here in the UK, using recycled metals and VOC-free inks. They offer the look and charm of traditional enamel pins while being significantly kinder to the planet.
