Osborne Reef Tire Cleanup 4ocean crews are diving to new depths to clean the ocean and protect our coral reefs from millions of tires that were sunk into the ocean over 50 years ago. This historic underwater cleanup is funded through the sale of the Osborne Reef Jewelry Collection, which is made with rubber from the tires recovered. After months of research, relationship building, and a lengthy permitting process, 4ocean was finally granted the licenses and permits required to dive the reef and recover these tires, and Halcyon Dive Systems and Garmin have supplied our teams with the proper tools to undertake this mission safely. -Handcrafted by local 4ocean Bali artisans -100% recycled stainless steel charms -96% (post-consumer) recycled content cord -Made with verified 100% recycled crumb rubber from tires that crews recovered directly from the Osborne Reef -Cord contains plastic collected by 4ocean captains and crew -Unisex, waterproof, adjustable from 7 to 13 in.
