SINGLES(2) 5/16" White MOP Vintage SWANK Formal Tuxedo Prom Shirt Stud a266

(Color: silver, white, (gold tone backs/workings). 5/16" or 8mm). I always try to point out any clear blemishes and condition. 0.25" = 1/4" or 6mm - pretty small for standard button holes. 0.38" = 3/8" or 9mm - also fits standard button holes.
