【Excellent Condition】This is a swaddle called Nekurumi, which I received as a gift. It seems the retail price is 5480 yen per piece. I opened it, but I have never used it. 【Size】M (6-9kg) Babies, usable from birth up to 9 months. I have experience using the same product, and changing diapers in the middle of the night was very easy, and my child would fall asleep quickly. Thank you for looking.
