In 1989, in Japan alone two million ivory name chops were produced. Currently Japan allows trade in ivory name chops of up to ten tons. One person at a large name chop firm in Taiwan does not even try to deny that his firm has more than 1000 tusks in stock.
根據統計，一九八九年，日本就篆刻了兩百萬枚象牙印章，目前日本國內每年仍以十噸數量交易中；台灣一家大型刻印店也毫不避諱地表示，庫存的象牙有一千多支，等於五百隻大象所提供！
