Cotton sleepers with a front-opening design for comfortable wear. This is a set of 4. My twins and I used these for rotation, including for washing. I think they were worn from around 4 years old to about 8 years old. This is approximate, but please use it as a size reference. Quilted knit sleeper, size M. They are all the same size, but due to shrinkage, they are slightly different in size. About 1-2 cm? They have snap buttons, so children can do them themselves. Made of 100% cotton, they can be used in spring and autumn, and for preventing chills from air conditioning in the summer. They have been well-loved, so there is a feeling of wear. There is some looseness, pilling, and fading. There is also fading along the fold line on the back. One piece has a light brown stain. It is faint and not very noticeable. (Photo 7) Please understand that these are used items that have been well-loved and may have some stains. I had applied masking tape with a name written on it to the tags, and when I removed it, the name transferred to the tag. The printing has also faded. They were about 2000 yen each. It seems like a waste to throw them away, so I would be happy if someone could use them again!
