I have never used this item since I purchased it. My memory is a bit hazy, but I believe the fur is rabbit fur. I apologize if I'm mistaken. The length can be adjusted using the metal hardware. The shoulder strap appears to be a dark brown color. Size (measured flat): Width: Approximately 27cm Height: Approximately 20cm Please forgive any errors due to amateur measurements. Since I haven't used it, it has been stored at home. I would appreciate it if you could understand this.
