I had an old wide buckle and it was the only black leather strap which matched my buckle and fitted perfectly.There was a small silver rod in the kit, I don't know what it is for.The leather looks high quality and I hope it will last a while.
Pros
Belt size 90: length 105 cm/41 inch for waist size 30-33. Belt width 38mm/1.5" for buckle 39-40mm (inner width). The belt is about 3.7mm thick.
