Hand Made in Italy

Only top quality materials, from certified companies for each material are employed, an entirely Italian production chain: wearing Piero Massaro eyewear is donning the warmth and creativity of the Belpaese.

The cellulose acetate

The eyeglasses of the designer Piero Massaro, are exclusively made of cellulose acetate, the only plastic material that comes not from petrol but from plant matter such as cotton staple fiber. In particular, Piero Massaro, uses the rhodoïd, the most precious of all cellulose acetate, as it allows to get amazing, three-dimensional and incomparable colour effects. It’s different from any other material for its transparency, its brilliance of the colors and its magical compositions. Its vegetable origin is also revealed to the touch, with a pleasing warm and silky effect.

Moreover, its production process, while integrated with the most advanced technology, is still closely tied to the manual ability of the best artisan tradition.
The peculiarity of this material allows to work the glasses by hand and thus to offer a really “handmade” piece.


The frames are not painted but polished by “tumbling”; frame and temples are placed in special barrels (tumblers) containing fragments of plastic, beech and birch wood, and shaped abrasive pumice that rotate continuously for several days (three to seven to get the effect), rounding off carefully the different components.

The finish

To give the eyewear the distinctive sandblasted effect, they proceed with the “blasting”, a mechanical process by which they erode the very top layer of glasses by abrasion obtained with a very thin jet of sand sprinkled on the manually placed glasses , one at a time, in a special machine. Finally, the polished effect of some parts is obtained manually working on the part to be polished with cotton and abrasive paste wheels, covering the part of the glasses that must be blasted with masking tape.
