These cufflinks are again from the estate of a gentleman I personally knew.
They are oval, measuring 20 MM x 13 MM; 16 MM from top of link, to bottom of crossbar; crossbar is 15 MM; shank is 13 MM. Shanks, crossbars, all nice and tight.
I would rate these items in very good condition; there is some scuffing on the topside of the ovals, not major, realize that these have been worn for 35 years, pretty good shape for that! No major scratches. Could be buffed, if you like.
Total shipping/insurance for the pair will be $3.00 for all USA shipments. Foreign shipments, inquire as to shipping method and pricing.
