Nikon Extension Ring E2 with Box and Manual

Nikon E2 Extension Ring
Comes with the original outer box (inner box not included, box is just the shell) and instruction manual.
Please research the details yourself.

The instruction manual and box have scuffs, yellowing, etc., as shown in the photos.
The extension ring itself does not seem to have any major issues.

For shipping, the box may be flattened and sent due to minimal packaging.
Please understand this in advance. I am also listing a set of two PK-13 extension rings at the same time. If you wish to purchase them together, there is a possibility of a discount equivalent to the shipping cost, so please contact me via message to discuss.

I kept it for a long time thinking it might be necessary, but since I rarely do close-up photography, I have decided to part with it. I would be happy if it goes to someone who needs it.

I strive to inspect items carefully and describe any points of concern in photos or text, but as this is a used item from amateur storage and listed by an amateur, please thoroughly check the information beforehand and purchase only if you are satisfied. To prevent issues such as product swapping, returns are generally not accepted, so please be aware of this.

Shipping will be via Mercari delivery service.
The carrier (Japan Post or Yamato) may be changed at my discretion.
To minimize shipping costs, the item will be packed as compactly as possible while ensuring protection.

I often use recycled materials for packaging if they are in reasonably good condition. For items that may shift inside the package, I may fill the gaps with newspaper or bubble wrap. Some people have complained about having to dispose of these materials, but I hope you will understand that it is better than the product being damaged.

Before purchasing, please be sure to check the profile description.
It summarizes my requests regarding transactions.

Thank you.
