I wore this for about a month after purchasing it. I think there are no noticeable stains, but please check the condition in the photos. The size is indicated as a guide for up to 80cm. This is a 2-way sleeveless sleeper (wearable blanket) vest and romper made with cotton blanket material, designed for long-term use. With sleeves, it keeps your shoulders warm even in the cold midwinter! The 2-way design allows you to choose between a vest or romper sleeper by adjusting the hook position. You can use it as a romper when your child starts walking, and as a vest when they get bigger. The sleeper is made from 100% cotton blanket fabric, which is highly absorbent and less prone to static electricity. We have carefully considered minimizing the burden on your child's skin by using a single piece of fabric and eliminating the seams on both sides (under the arms). Cotton products are excellent at absorbing moisture, retaining moisture, and allowing air to pass through, so your child can sleep comfortably, and even children who move around a lot in their sleep can use it with peace of mind. Recommended as a gift. 【Washing/Care】 We recommend hand washing, but if you use a washing machine, put it in a laundry net and wash it with plenty of water using a delicate cycle or similar. Wring out the water just enough to remove excess moisture. The fabric is 100% cotton, so some shrinkage may occur due to washing. The color will gradually fade with washing.
