Continuous spiral of heavy brass rod wound around the neck, added to over years so that the collarbones are depressed and the neck appears elongated. Practised by Kayan Lahwi women specifically, not by all Kayan or all Karenni. ETHICALLY SENSITIVE because of exploitative long-neck-village tourism - a marketplace should handle replicas and imagery carefully and should not list worn coils as souvenirs. Made by a specialist smith, not woven.
