This is a new reproduction of the small binocular case used by British officers in the Boer War, Colonial Wars, and WWI.  It is made of real leather from actual animals.

Inside dimensions are 6 inches by 2.5 inches. The carrying strap measures 64 inches.  This case is designed to fit old style non-prismatic "barrel lens" small binoculars.

The last photo shows the binocular case next to a water bottle for size comparison.
