An estimated 200 billion cardboard boxes are shipped around the world annually, and most of them are used just once before ending up in landfills or the ocean. Boox is the first shipping box specifically designed to be used over and over again. After unpacking their items, customers fold the Boox flat, scan a QR code and send it back to Boox with the included return label, no other box or envelope required. Constructed from polypropylene, most Booxes ($1–$2.50 per shipment) can make more than 20 journeys before being recycled. Since its launch in 2020, the Boox has been adopted by retailers like Sephora and the women’s denim line Boyish Jeans, contributing to the more than 125,000 estimated Booxes sent to every U.S. state and more than 20 countries. —Mariah Espada
