Thank you for viewing from among the many items available. GoPro Hero13 Genuine Lens & Genuine Battery Cover Set There are scratches on the plastic part of the side of the lens, but there are no scratches on the lens surface, and I think the condition is good. I also replaced the side door with a charging-through type after purchase and stored it, so I don't think there are any noticeable scratches or anything that would impair the waterproof function. Please check the photos. Since it's not a third-party product, I don't think it's often put up for sale. Don't miss this opportunity! "It's reassuring to have one for insurance" I think it can also be used for Hero9, Hero10, Hero11, and Hero12.
