I purchased these new in October 2024 as winter underwear, but my child tends to get hot and they didn't suit their skin, so I switched to mesh underwear and stored these. Some have been worn once or twice, and some have only been washed. Most haven't been worn. The car pattern in images 2, 3, and 4 is from Nishimatsuya. The bear pattern in images 7, 8, and 9 is from Shimamura. They have been washed, but since they are for a baby, I recommend washing them again at home before use. There are no smokers in the house, but we have a dog. We take the utmost care to prevent pet hair from sticking, but there may be oversights. Please be aware of this if you are concerned or have allergies. Thank you for looking.
