Please be sure to read the seller's profile first. This is a set of two genuine white-painted tripod mounts for Canon EF L-series lenses. The items are from the seller's past new purchases of the 70-200/2.8L and 300/4L IS lenses. Since they have never been used as tripod mounts since purchase, the seller has decided to sell them. Both are the same. The current condition is that the tripod mount function is perfect, but there are slight scratches on the edges of the tripod attachment part and some paint peeling. These white-painted tripod mounts for L lenses are already discontinued by Canon.
