Here is a set of three 80-size Nishimatsuya rompers that I received. I was given these as unopened items, but after opening them, my child outgrew them before they were hardly used, so I am selling them. They are long-sleeved rompers made of a thin, smooth material. I think they would be good to wear as underwear during the cooler months. I want to sell these quickly, so feel free to comment! I am also selling other baby clothes, and I welcome combined purchases! Please only purchase if you understand that these are used items.
