buffalo horn has a long tradition in the manufacture of eyeglasses in europe. its exquisite colouring and natural lightness make for truly luxurious eyewear. we source our horn exclusively from buffalo who have lived long, natural lives; only then is the horn humanely and respectfully removed before being lovingly handcrafted into its next life.


the stainless steel parts in onono frames are pvd-coated (physical vapour deposition) with colour, the microscopic molecules deposited directly into the surface of metal. we use only the noblest, most luxurious compositions such as gold, ruthenium and titanium.
