This is a custom-made card case of a white Java sparrow, ordered about 7-8 years ago from a leather goods shop in Adachi-ku. I requested that they make a card case modeled after a white Java sparrow. I used it for about a year and then stored it carefully. The price was 11,000 yen. There is a punch hole at the top, so you can thread a string through it and use it as a neck strap. It's very lovely. How about it, bird lovers? I wiped it down before listing it. Size: Length: 10 cm, Width: 7.9 cm *Please note that there may be slight variations in size.
