I purchased these about three years ago, probably at Akachan Honpo, Birthday, or Nishimatsuya. I opened the packages after buying them, but as far as I remember, I wore the postpartum underwear given to me at the hospital, so these are unused. Some still have tags attached. Postpartum Underwear - Size: M-L - Quantity: 7 pieces - Colors: Gray, black, light blue, floral patterns, etc. - Material: 100% cotton Soft cotton M-size maternity innerwear. Thank you for looking.
