Made using recycled rubber from tire sidewall, with an imprinted recycled aluminum plate bearing the word "green.", this chunky wrist piece works well for both men and women. Each bracelet's rubber strap is slightly different due to varying graphics and textures of the tire sidewall used to make it, however all bracelets are primarily black. $10.00 from each bracelet sold will be donated to environmental groups including Earth Share, the Natural Resources Defense Council; Global Green; Healthy Child, Healthy World; Stop Global Warming, and many more. Show your true colors, and make them GREEN.
