Newborn Size Short Kimono-Style Undershirts, Set of 4 These are short kimono-style undershirts that came in sets purchased from Nishimatsuya and Akachan Honpo. I didn't use these undershirts, so they were stored separately in a bag, unused. One item is from Hot Biscuits, a gift. All are size 50. There are no yellowing or stains. They are in good condition, but please refrain from purchasing if you are sensitive to such things.
