urchin bags are made from 98% recycled materials, and are 100% unique. urchin bags are created with reclaimed car seat belts, used bike inner tubes, scrap vinyl, old banners and boating materials. Don't worry, all materials have been scrubbed! I am always searching for other materials that can be salvaged before they head for the landfill. All urchin bags are made using the colours and materials found at the time of creation, so keep checking my on-line store for the latest bags.
