Pairdet titanium are above all marked by their workmanship. Their elaborate surface treatment makes their hardness, adhesion, resistance to solvents and perspiration tests unique. The layer thickness is precisely predetermined at every point of the frame, right down to the rim, by way of cathodic dip painting. Colors are always applied manually. This makes each pair of glasses a unique product. There are also special varnish inlays which look like little jewels but are considerably more durable.
