KENKO N-AF UNIPLUS TUBE 25 FOR NIKON MACRO PHOTOGRAPHY

This is Kenko's Digital Macro Extension Ring 25mm for Nikon AF, which is attached between the camera body and lens to enable macro photography (close-up shots).

I purchased it for close-up photography.
For a while, I was into shooting plants and used it to photograph petals and leaf veins, but I no longer need it, so I am selling it.

I could not find any mold or scratches.
There are some slight scuff marks on the metal parts.

Included are the front and rear caps.
If you wish, I can include the pouch shown in the image, but it has developed a peculiar odor from being stored in a camera box.

It's an odor from when I bought it at a second-hand shop.
(I'm sorry!)
If the odor doesn't bother you, I will send it along with the item, so please let me know.

Thank you.
