This is a combo undergarment with a bear pattern from Nishimatsuya. I used it during the newborn period. The bear pattern is very cute, so I think it can be worn cutely by both boys and girls! It's 100% cotton, so it's safe. It has been washed at home with baby detergent. Since it has been in someone else's hands once, please refrain from purchasing if you are sensitive to used items. Also, please refrain from purchasing if you are extremely concerned about folding wrinkles. It will be protected from water damage and shipped in an envelope. Discounts are available for purchases with the koala-patterned combo undergarment, which is listed separately.
