I HAVE HUNDREDS OF TIE TACKS, TIE BARS AND CUFF LINKS. collar bar: none. I always try to point out any clear blemishes and condition. tie tack/bar: 1.98" x 1.01" (2" x 1" or 50mm x 25.5mm). 0.25" = 1/4" or 6mm - pretty small for standard button holes.
This product would be a great fit for corporate business meetings, promotions, or events where a unique and stylish logo tie bar clip is desired to showcase company branding.
