Set of 4 Vintage Brass Cigarette Snuffers Kiwi Birds New Zealand

vintage very shiny brass kiwi birds on a base of epoxied crushed abalone shell marked New Zealand I believe these are cigarette snuffers the hole in the back is for the cigarette to go into to be snuffed ~ only one appears to have been used (pictured) regardless, they're very beautiful quite heavy, I think they're brass (not magnetic) in great vintage condition measure approx 1.5" long x approx 1.25" tall
