These are pants from Lowrys Farm. The size is F. The color is black. I bought them a few years ago for around 5000 yen. They don't have tags, but they are unworn, only tried on. The back of the waist is elastic (see photo 4). I don't think there are any noticeable stains, but please understand that they have been stored at home. They will be folded small for shipping. I plan to use Yu-Packet Post, but depending on the packaging, I may change to Takkyubin Compact or Yu-Packet Plus.
