Oscar Deen Pinto Sunglasses - Treacle All Oscar Deen  frames are made from Mazzucchelli acetate. They're Italian and have been top of the game since 1849. While their lenses are made from organic plastic. A combination of light-weight and optical clarity. Inspiration: From the 40's and made in France. A classic shape called Crown Panto, misread by one of us as Pinto. Now: A slightly raised key hole bridge and complimentary lower frame that mirrors an angled brow. We weren’t about to spend all this time creating bespoke frames to then dash them in some off the shelf case.  The OD case is made in collaboration with London based leather artisan and mate, Otis Ingrams Each one is hand made in London, from 2 pieces of recycled composite leather, 4 brass rivets and one brass stud.
