This is a set of 6 combi-style undershirts. Photos 2 and 3 are from Petit main, and photo 4 is from Nishimatsuya. The Nishimatsuya combi-style undershirts are made of organic cotton. Petit main was used for my first and second child, and Nishimatsuya was used only for my second child. Both were used from newborn to about 2 months old. There are no noticeable stains or dirt, but please refrain from purchasing if you are concerned. Shipping is planned via Rakuraku Mercari Bin or Yuuyu Mercari Bin.
