Great addition to the Mahjong Collectors collection. These tiles are made from resin/plastic - they are not real mahjong tiles, they are about 1" in size and they dangle with a bead from a 18" stainless steel chain. ***We are more than happy to make this necklace in sterling silver. However we will need you to reach out to us for pricing on sterling silver for a custom order. Comes carded and packed in anti tarnish bag.
