She bought this for around 4,000 yen, but apparently forgot about it and bought something else, so she asked me to list it. As stated above, it is unused. Since I didn't purchase it myself, I lack some information, but the surface has a leather-like texture. The back is not like that leather. Inside, there's a pouch with a similar leather-like texture, which I thought was convenient. It seems she bought it at MOGU.
