Those cufflinks are bad. Why don't you buy double-sided ones? They are much more elegant. And with all the gorgeous antique pairs in Europe, why are you buying contemporary ones? You can find much, much better examples of antique double-sided ones for less than 67 Euros. There is no pride in overpaying.
I don't like double sided = - they are not practical at all to put on - i know i would pull on the chain to see if it is strong and i would break it (i am used to make test of strongness.) I don't like old cufflinks smelling metal, with stains and scratches showing pictures of countryside, animals or men in tights... I like modern silver rodhium plated cufflinks with stone or with something original. 67 euros for silver links plated with rodhium and enameled Â with 2 years of warranty sounds fair.
