Your Oscar Magnuson frame is an all-natural product. It is handmade from bio-acetate by highly skilled craftspeople in our Italian factory. The bio-acetate, deriving from wood and cotton fibers, gives it an exclusive touch and a sense of warmth and silkiness, which can only come from natural substances. Our bio-acetate is 100% eco-friendly, 100% biodegradable and 100% recyclable. Oscar Magnuson frames come encased in 100% organic leather sourced from the Swedish tannery Tarnsjö Garveri.
