I HAVE HUNDREDS OF TIE TACKS, TIE BARS AND CUFF LINKS. cuff links: none. tie tack/bar: 0.71" x 0.75" (11/16" x 3/4" or 17.5mm x 18.5mm). collar bar: none. I always try to point out any clear blemishes and condition.
This product would be a great fit for those looking for a fashionable and meaningful lapel pin to commemorate two years of their Master Naturalization Certificate (NMC).
