This is a 2" (5cm) belt strap. It is made of a 2 inch strap of leather.
It features 5 punched holes approximately 1 inch apart on the strap, and includes 2 screws to fix your buckle to the strap.
Please indicate the required waist measurement in inches or cm (taken around your naval). The actual strap length will be long enough to go over a sash and then have enough to tuck under itself as in the picture!
