I HAVE HUNDREDS OF TIE TACKS, TIE BARS AND CUFF LINKS. tie tack/bar: 1.70" x 0.63" (approx. 1-11/16" x 5/8" or 43mm x 15.5mm). collar bar: none. 0.25" = 1/4" or 6mm - pretty small for standard button holes.
This product would be a great fit for aviation enthusiasts who are fans of the Pratt & Whitney logo or vintage-style designs.
