This is a set of two combination underwear (konbi hadagi). They are a comfortable thickness and have a smooth, cool feel. I live in Hokkaido, and I used these for sleeping after my baby graduated from swaddles but before using a sleep sack! They haven't been worn many times, so they aren't worn out, but they are not new, so please understand that they are used. *Upon close inspection, there is a faint stain on the left chest area of the white star-patterned item. I have added a photo. - Color: White, Mint - Design: Star pattern, Solid - Size: 50-60 - Type: Combination underwear
