Extension Tube Nikon F Mount Macro

This is an extension tube that turns your existing lens into a macro lens. It comes in 1.2.3, so please adjust the focal length to use it.

I bought it new but immediately purchased a macro lens, so it has only been attached once.
This is for Nikon F mount.

Also, if you are unsure how to use it or are sensitive about scratches, please purchase a new one.

It functions normally, has no lens inside, and is made of metal.
