It's approximately 22.5 cm to 18.5 cm in size. I bought it for my Chihuahua, but I only used it for a few hours and have kept it stored for 2-3 years. I'm selling it because it's too small now. It was custom-ordered from Kiminofuku and has "KOMUGI" (wheat) written on it in Roman letters. It's made of leather, so it's quite sturdy and can be enjoyed for many years. I also chose the color of the stitching thread, making it very cute. It cost 8800 yen.
