This Old Bronze Opium Weight Set is a collectible Asian antique that consists of 9 elephants. The handmade set dates back to the late 19th century and has a brown tarnished color. The weight type is suitable for antique collectors and enthusiasts who are interested in Southeast Asian antiques. The primary material used to create the set is what I believe to be bronze, and it is an original piece. The region of origin for this antique is Southeast Asia, but it has no maker marks. The two smallest ones have a smaller hole and will link with each other but not the others.
