I HAVE HUNDREDS OF TIE TACKS, TIE BARS AND CUFF LINKS. I always try to point out any clear blemishes and condition. tie tack/bar: 1.34″ x 0.60″ (1-5/16″ x 5/8″ or 33.5mm x 15mm). collar bar: none. GOOD – used, showing age appropriate signs of use such as minor scratches and minor wear, no cracks or missing pieces.
