ASAHI-PENTAX 110 Close-up Lens Filter

This item is from a decluttering of my parents' home.
To the untrained eye, I see no scratches on the lens, but this is purely an amateur assessment.
I have no idea what kind of camera or lens this is for, so please judge from the photos.

If you are sensitive, seeking perfection, or have even the slightest concern, please do not purchase this item.

*Negotiations for a reasonable price reduction are welcome.

I will wrap it all together in bubble wrap and ship it via Nekoposu.
