Black cord, black beads make this well, black on black! The cord is 3 mm polyester and the beads are plastic so it is all organic but not grown in a field or made in a furnace. Yeah maybe this isn't for everyone but there are other offerings that are made of natural cotton and glass. Look around!
This is on the large side of "medium" at 7 3/4" inside circumference right for a larger adult hand. Smaller and larger sizes are available by request.
