Featuring my take on a da Vinci classic, these pins are made from 100% premium recycled acrylic. Plastics nearing the end of their usable life cycle were repurposed into 3mm sheets from which the pins were cut. That means each purchase keeps a wee bit of plastic from ending up in a landfill. Acrylic pins are an environmentally-friendly alternative to enamel pins (using more than 300% less water to manufacture) but retain the same colorful, high-quality finish. The pins have classic butterfly backings and are approximately two inches tall.
