This is a marbled cream corn color (I think white underneath) vintage Bakelite heart button. This is new old stock NOS, it has never been used, it is in MINT condition. I believe it is European in origin, it has a different type of metal shank than your typical USA button. This has a nice thickness and is slightly beveled on the edge; it measure 7/8”.
Please feel free to ask me any questions that you may have. I will ship this item 1st class, domestic or internationally. See more charms, buttons, jewelry, and Bakelite Bits in my shop. Thank you for visiting! Cher ♥ BakeliteBits.com
