Kids Sleeper With sleeves Long sleeves 1.5 years old, 2 years old, 3 years old, 4 years old, 5 years old 90, 100, 110, 120 cm Gauze, Organic Cotton Cotton Haruulala This is a thick cotton sleeper. I purchased it new on Rakuten (about 6000 yen) and wore it in combination with other items during the winter for one year, but I am selling it because my child has outgrown it. Since it is made of cotton, it is breathable and easy to use. It is a free size, and you can use it from a young age by fastening the bottom, or up to around 120cm by wearing it like a gown without fastening the bottom buttons. I only used it when sleeping, so I don't see any stains, but I apologize if I missed anything. Please purchase if you understand. #Sleeper #OrganicCotton #LongSleevedSleeper #Cotton #Haruulala
