This is a CONTAX 1A 86mm lens filter. I am listing it as I am organizing my grandfather's house. It has been stored in its case and is likely unused. However, since it cannot be definitively confirmed as unused, I have set the condition as "Near Mint". As there are no family members who are camera enthusiasts, I would like to pass it on to someone who can use it. I believe it is quite clean and can be called a beautiful item. Please check the condition in the photos. Thank you for looking. I look forward to your consideration.
