Hand crafted, fair trade. Produced by a company with a decades long relationship with a single village in Thailand. Over 400 neighbors in this rural land work together to produce the art pieces, including a total of 15 master artisans. Metal designs are composed of three different metals--nickel, copper, and brass. There is no lead or any other harmful substance in the metals; all metal pieces are designed to be safe as possible, with a minimum of sharp corners and edges. Only lead free solder is used.
