MINOLTA Close-up Ring No. 1, 2, 3 Set

Thank you for looking.
This is a set of Minolta extension rings. These are products from around 1955-1960. I used them when I was young, but I can't find the lens, so they've been stored away in a drawer.
I'm selling them as part of decluttering.
While it's not the original case, I have a Minolta case, so I plan to ship them in this case.
The maximum outer diameter is 60mm, the inner diameter is 38.6mm, and the length is 44.3mm. Although they are old, I believe they can still be useful to someone who owns a lens.
