Hi, all, I have a pair of Tiffany cufflinks in the classic and discontinued "Nut and Bolt" design. Hallmarked and .925 solid sterling. Worn very little. Sorry, no little blue box. Payment by PayPal and shipping free but only to CONUS, please. Guys have these on sale on eBay for almost $500 (not that they are moving at that price.) Mine are also listed there if you are international--I would ship through their program. Haven't bought or sold here in a while, but I am reliable. Thanks!
