Rare Kenko Monocular 7x18 Made in Japan (Vintage) Unused Stored Item

This is a monocular made by Kenko, found while tidying up my parents' home.

[Product Condition]
This item was purchased and stored by a relative. I haven't used it myself, so I'm unsure of the exact purchase date, but based on my inspection, it appears to be deadstock (unused) with no signs of use.

・Operation Check: I've confirmed that it focuses when looking through it. The lens is scratch-free and very clear, making it fully functional.
・Main Body: The rubber on the side shows faint white discoloration due to age, which is common for older rubber products. It is not sticky.
・Outer Box: The outer box shows significant signs of age, including yellowing, dirt, and damage from long-term storage (please refer to the photos).
・Accessories: Original case, instruction manual, and strap.

[Recommended Points]
This is a well-made model that originally retailed for ¥7,800 (excluding tax). It has a more robust construction than current inexpensive monoculars and has a charming retro aesthetic.

[Shipping & Packaging]
To minimize shipping costs, I will send it via Yu-Packet Post Mini. The outer box will be carefully folded and included, and the monocular will be shipped in its original case.
(Please let me know in the comments if you do not need the box.)

・Rest assured, it will be securely packaged with moisture protection (OPP bag) and bubble wrap.

[Notes]
Although it is unused, it is an old item that has been stored at home for a long time. Please only purchase if you understand and appreciate vintage and retro used items.

Immediate purchase is welcome. Thank you.
