Cat-pattern pajamas made of a smooth material. These are used items that have been used several times. They have been washed. I usually wear size M, so I think these are M, but the size tag is completely unreadable. There are some loose threads. Please see the photos. The condition is not good, but I will sell them only to those who still need them. I will not be lowering the price at this time. Please be sure to read my profile before purchasing. Color...Blue系 (Blue-系) Sleeve Length...Long sleeve Season...Autumn Stains, tears, odors, etc....None
