Made in Japan, 100% cotton. I think there are no noticeable stains overall. It seems to be very comfortable with soft cotton. I wore them several times when my older child was a baby. My younger child outgrew them without wearing them because the season didn't match. Both are size 70, but they run small. I think they're suitable for newborns to babies around 6 kg. The sleeves are long, so they should fit babies up to size 70 if they are slender. At 4 months and 7.5 kg, my chubby baby couldn't close the buttons at the feet. - Colors: White, Pink, Beige - Design: Animal print, Dot pattern - Material: Cotton - Quantity: Set of 2 Thank you for looking.
