These are black pants. I selected size M, but the label says the waist size is 66-70cm. I chose M because that's my usual size. They appear to have been worn a few times, but the exact number is unknown. I've been wearing a lot of dresses lately and not many pants, so I'm selling these to reduce the number of pants I own. The tag is in good condition, so I believe they haven't been worn much. There are some loose threads, which seem to be from the beginning. They are present in areas other than the part shown in the 7th photo. I can add more photos if you'd like. The back of the waist is elastic. Shipping will be in a zip-lock bag, via either Rakuraku Mercari Bin or Yu-Yu Mercari Bin. I will remove the air and seal the bag, so there is a possibility that the pants will arrive slightly wrinkled. Thank you for your understanding.
