Thank you for viewing! This is perfect for those expecting a baby during the chilly season and winter! This is a set of 9 items purchased from Nishimatsuya: Two-way alls: 6 Rompers: 1 Combi underwear (warm material): 2 All sizes are 50-60. Materials: Two-way alls: 4 are 100% cotton 1 is 65% polyester, 35% cotton 1 is 60% cotton, 40% polyester Romper: 100% cotton Underwear: 100% cotton While I've inspected them and found no noticeable stains, they do show signs of wear. There are fold marks, some slight pilling, and some pilling on the bear-patterned item. The two-way wear can be converted from a dress-all to a coverall, so it can be used from the newborn period until the baby starts kicking their legs. All the wear was worn for about a month. The underwear is made of a slightly thicker fabric, which will be useful in the coming season. They are the tie-up type. These were quickly outgrown, so they were only worn for about half a month, and are in good condition. They have a retro pattern and are cute. Although they are used, I think they can still be worn! Newborns change clothes many times a day, so if you don't mind used items, please consider them! I think the colors and designs are suitable for both boys and girls.
