This is a set of 77mm and 67mm PRO1D protectors. These are filter sizes suitable for full-frame camera lenses. I have only used them a few times, so I am offering them for sale. There are no noticeable scratches or stains on the filters or metal parts that would interfere with photography. Regarding the 77mm PRO1D protector, I do not have the original case, so I will ship it in another filter case. ※See photo 2 If you have any questions, concerns, or would like additional photos, please feel free to ask in the comments. Regarding shipping, I plan to wrap them in bubble wrap and send them in a large envelope.
