Clean the ocean and protect our coral reefs

This 18” box chain necklace is made from recycled stainless steel. Designed to represent the tires we’re recovering from the Osborne Reef, the tire-shaped pendant is filled with verified 100% crumb rubber from tires that our crews recovered directly from the Osborne Reef. 

The tire crumb is set into the pendant with our plant-based epoxy resin. The outer edge of the pendant is etched with tire-tread detail and the back with 4ocean branding. Every necklace purchased supports the growth of the Osborne Reef Tire Cleanup and helps protect our coral reefs.
