Vintage lens cap made by Asahi Pentax, for M42 screw mount lenses. This cap was originally attached to a 55mm lens, but may also fit other lenses of the same type. Please check the size and compatibility before purchasing. It shows signs of use appropriate for its age, but the "Asahi Pentax" logo is clearly visible, and the condition is good. Please check the photos for the external condition and make your judgment. Please refrain from price negotiations. Also, returns are not accepted.
