Thank you for viewing. Please refrain from comments asking for a price reduction. Canon lens rear caps. A set of 2 EF mount (genuine) and 1 RF mount (third-party). I am selling these due to the sale of my Canon equipment. Regarding the third-party RF mount, it appears to be for Canon, but I cannot verify this as I do not currently have any Canon lenses. Please understand this. I cannot accept returns even if it is different. Everything in the photos is included. The items will be delivered as they are. Please understand. Please purchase only if you understand. No claims and no returns to prevent swapping. There may be other minor scratches or stains that I have overlooked. Please refrain from bidding if you are sensitive to such details.
