Thank you for viewing! These are Uniqlo pajamas made of quilted material. I wore three sets of pajamas, including these, throughout one season, but I didn't eat while wearing them, so I don't think there are any major stains. There is some wear and tear, but there are no major stains or stretched-out elastic, and I think they can still be used. How about these for a child who loves Paw Patrol? Thank you very much.
