Thank you for viewing. This is a genuine Canon EF 70-300mm F4-5.6L IS USM dedicated ring-type tripod mount ring TRIPOD MOUNT RING C (WII). [Product Overview] https://store.canon.jp/online/g/g4429B001/ [Condition] I purchased this tripod mount ring earlier, but I no longer need it as I didn't buy the lens I intended to. There are two small, approximately 1mm scratches, but it's in very clean condition with no shine or other damage. I am confident in offering this item, but please refrain from purchasing if you are looking for a perfect item. Thank you, and I hope someone can use it.
