Pentax SP Close-up Ring Set of 3 with Dedicated Case

3-piece macro ring set for Pentax SP, with dedicated case.

- Type: Macro rings
- Quantity: Set of 3
- Accessories: Dedicated case
- Size: For compatible lenses

Thank you for looking.
This is a set of 3 macro rings purchased for the standard lens of the Pentax SLR camera SP, which was a big hit decades ago. There are no noticeable scratches overall, and I believe the leather case is also in good condition.
I would like someone who is a fan of the SP to use these. I will sell them to someone who understands that they are old used items.
