This is a 6-piece set including pants purchased from MUJI. While none of the items have stretched-out elastic that makes them unusable, please consider the extent of the stretching to be based on a personal inspection. All items are stored at home and have been personally inspected. All items have been worn a few times. Thank you for your understanding. Tags with names written on them will be cut off. These are the parts with the size and washing instructions, so please refrain from purchasing if you are concerned. All sizes are confirmed to be 80. There may be slight differences in the color of the fabric due to the lighting. Some items may show noticeable pilling due to the characteristics of the fabric. Thank you for your understanding.
