Thank you for viewing! This is a genuine Canon lens hood. I purchased it new from Camera Kitamura and used it with the EF70-300mm F4-5.6 IS II USM. When not in use, it can be mounted in reverse on the lens, which is convenient and doesn't get in the way. It offers the stability you'd expect from a genuine product. Compatible lenses: RF100-400mm F5.6-8 IS USM, EF70-300mm F4-5.6 IS II USM (from Canon's website) There are some minor scratches on the surface, but I think it's in relatively good condition. Please understand that this is a used item and has been stored at home before purchasing. Shipping will be via anonymous Rakuraku Mercari delivery. #Canon #Genuine #LensHood
