This sale is for a brand new, unused rear lens cap for the Mamiya 7 and 7ii 43mm, 50mm and 65mm lenses.
This is an essential item for use when the lens has been removed from the camera. This (much deeper than the 80mm) cap can be used on all Mamiya 7 lenses, including the 80mm, 150mm and 210mm. Try finding another one – almost impossible to find. This example is new and in the original unopened bag, but does have avery small scuff on the rim from poor storage where the bag has partly split open.
