NOS Carded Costumakers Buttons Made In Japan 4 Shiny Blue Moonglows, with what appears to be geometric straight lines compressed/made in the buttons. I took several pictures, in hopes of showing the geometric lines in the buttons.

  I am not certain of material made of, but seems to be plastic with clear plastic shank.

 On original card,  which says, 34 ( 7/8"). Also, marked "Japan." Slight stains on card, but does not affect buttons.
