Internal measures: Height: 6 and 3/4 in, diameter: 2 and 3/4 in

Originally for Sigma 75-300mm zoom lens. But it can be for any lens with height 6 and 3/4 in, diameter 2 and 3/4 in or less.

It was very lightly used, supper clean, overall in mint condition. It does show minor rusty on the 2 strap rings.
