These were used by my father, who is a camera enthusiast. The purchase date is unknown. I am selling them as part of a decluttering effort.
Please check the photos for size and condition.
The boxes have some scratches, but I believe the filters themselves are in good condition.
I have no knowledge of cameras myself, so I won't be able to answer technical questions. However, I will add more photos to show the current condition as much as possible, so please feel free to inquire.

I am open to price negotiations for some items, so please feel free to comment.
When negotiating, please state your desired price, as it would be helpful.
Please only purchase if you understand that these are used items.
Those who are sensitive to such things should refrain from purchasing.
I will ship within 48 hours.
No pets, smoking, or perfume odors.
