I HAVE HUNDREDS OF TIE TACKS, TIE BARS AND CUFF LINKS. cuff links: none. collar bar: none. tie tack/bar: 1.02" x 0.54" (approx. 1" x 9/16" or 26mm x 13.5m m). 0.25" = 1/4" or 6mm - pretty small for standard button holes.
The "Claw Hammer Vintage Lapel Pin" is a fantastic choice for carpenters, builders, or DIY enthusiasts who prioritize style and functionality.
