I used these from newborn to about 3 months, and am selling them because my baby has outgrown them. The red patterned one is from Nishimatsuya, and the blue patterned one is a no-brand item. I've checked them myself, and I didn't see any noticeable stains, dirt, or fraying. The red patterned one has some pilling from washing, but otherwise, there are no issues. There is no name written on them. You can adjust the inner layer, so they can be worn from autumn to spring. *Non-smoker, no pets* *I am also selling these on other sites, so I may delete the listing suddenly. Thank you for your understanding.* Thank you very much! #Nishimatsuya #NewbornBabyClothes #Coveralls
