There are nice things

which - even if they are out of fashion for some time - always have a comeback: the suede pump e.g.  And the cufflink. Sometime such things are "Classics" ... they may change their appearance, get a little suited to the latest trend or design but in principle they remain what they are - themselves. So do our cufflinks. 8 models, with colored leather differently textured. On demand also inlays made from stainless steel or noble metal for engravings. 

One base body, one inlay and one frame and then turn. Inlays made from felt, leather, photo parts under mineral glass, plastic, metal plates with engraving ... and  so on ...

.... suitable as an inlay is all that you can nibble into a round chip of 14x2mm.
