Each bangle is unique, made from buffalo horn, with naturally dried lacquer. The dimensions vary slightly due to the handcrafted nature: XS: 57/60 mm S: 60-63 mm M: 63-65 mm L: 65-67 mm XL: 67-69 mm XXL: 69-72 mm The thickness is 6 mm. The horns come from buffaloes consumed for their meat, respecting an artisanal recycling approach in Vietnam. IMPORTANT: The animals are not killed for their horns; in Vietnam, the diet largely consists of this buffalo meat, and the horns are recycled in artisanal workshops.
