Another Frey & Winkler invention - the Primadonna is small and insconspicuous, and particularly suitable for thin eyeglass rims, the pad-arm diameter being only 1.0 mm. Fixing the Primadonna nose pad is fast and easy - forget the time-intensive screwing the nose pad in place. Another particular advantage is the nose pad's lateral mobility - adding wear comfort from all angles. No matter whether round, oval, drop-shape or trapezium-shape; made of silicone or PVC or metal; with or without air cushion - F&W not only offers nose pads, but also matching pad arms.
