The VF Buffs are named after the street slang of buffalo horn glasses. Buffalo horn was the original material used in eyewear production in the 1940s and 50s. Our detroit player drill mount buffalo horn edition features arms made of sustainably source, genuine buffalo horn, reinforced with 24KT gold hardware. Each VF buff shows a unique pattern as they come from different horns and come in a video box telling the story behind the frame.
