If you are a serious collector of Japanese flight related items, then you know there are only a handful of known examples of this extremly rare set of Japanese pilot goggles. Known as the “Takashimaya Flat Lens” these would’ve been worn very early on in the war years for cold weather to avoid frost burning the face. I can not stress how rare these goggles are, and stone mint. One would find it next to impossible to find another pair on the open market, let alone one in this condition. Do not let this rare item slip by, you will never find another pair.
