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: 2.38" x 2.40" (2-3/8" x 2-3/8" or 60mm x 61mm). 0.25" = 1/4" or 6mm - pretty small for standard button holes.
The "TH Monogram Initial Letter Vintage SWANK Pendant Chain Tie Bar Clip" would be an excellent choice for personalized gifts such as wedding favors or engagement party favors.
