There is some blackening on the corners, but I think it can still be used comfortably. The inside is also clean. There are two card slots inside. The approximate size is 10 x 16 cm. I think it can be used for various purposes such as a wallet, pouch, or handbag. Please check the details in the images. This item was previously purchased on Mercari, but I am selling it because I no longer use it. I will give it to someone who needs it. Please refrain from purchasing if you are very sensitive to details. Thank you.
