Thank you for viewing. This is a cordless electric slipper (with two 8000mAh batteries). Included are two spare batteries and two charging cables (USB-typeC). ▽Product Link https://amzn.asia/d/bXJ509B - Size: M - Color: Maroon Brown I wore these once and took a few steps, but I felt the size didn't fit, so I'm selling them. (I usually wear 23.5cm, but these felt a bit large.) They are in near-new condition, but they have been handled by a person, so please refrain from purchasing if you are sensitive to this. Operation confirmed. Separate sales and price reductions are not possible. They will be shipped via Mercari delivery service. If you have any questions, please feel free to comment.
