These beautiful vintage mother of pearl buttons are vintage Japanese and were made about 60 years ago. They are made from a luminous ivory mother of pearl, with radiant streaks running through the shell. They are carved in a diamond shape, with a second smaller diamond carved in the top. They measure 10mm or roughly 3/8 inch in length and are about 7mm or 1/4 inch across the widest part of the diamond. There is some variation from button to button as you would expect from this natural material. These are new old stock (nos), never used, coming off the original hank, tagged "Made in Japan". You will receive 6 beautiful vintage buttons.
