This is a KANGOL pajama set. Size is 110cm. It has good breathability and was useful on very hot days. Used for one season. There is no name written inside, but the pants only have quite a bit of pilling on the bottom (see 3rd photo). I don't think the top two items have much noticeable pilling. No smokers or pets in the household. To prevent returns due to swapping, we cannot accept returns. Please understand that there may be wrinkles from folding during shipping. This was used by a child and stored at home, so we ask for your understanding before purchasing. This item is also listed on other sites, so if it is sold out, we may have to cancel the transaction.
