The Build bracelet creates goodness on so many levels! Each three-stranded bracelet is not only handmade by women artisans in India, but it also provides funds to help restore forests. We donate 15% of the wholesale price of the bracelet to the National Forest Foundation. Donations are made based on purchase quantity, not product sales. Beads measure .125" wide and are made of glass and a brass/metal mix. Bracelets stretch to fit most wrists.
