Underwear set featuring designs of Minnie Mouse and Hello Kitty, made of 100% cotton. The set of 4 has been opened, and only the short-sleeved shirt has been used. The pants are unused and have been stored in their original bag. When shipping, I will open the bag and fold the items. Please understand. I think you might need a lot of pants for potty training, so how about this set? (^○^) Thank you for looking.
