I wore these, along with a few others, as pajamas on rotation for about two and a half months. There is some wear and pilling, but I think they can still be worn. I've included a photo (photo 5) showing some of the areas with a lot of pilling. I am selling items that I have determined are still wearable even if there are some loose threads. Also, there may be some creases from storage and packaging. If you are concerned about this, please refrain from purchasing. [Important Notes] I have pets (there is a possibility that I haven't removed all the pet hair) I am currently raising a child, so there may be delays in shipping Simple packaging and recycled packaging I will pack as compactly as possible (may compress items if necessary) The cheapest shipping method (usually anonymous shipping) As I am a private seller, there is a possibility that I may overlook stains, etc. Shipping method may be changed from Yu-Yu Mercari to Raku-Raku Mercari without notice I am not responsible for shipping issues Please be aware that I cannot accept returns or refunds. Please purchase only if you agree to the above. Thank you for looking.
