This is a Qsberry ZERO navy baby carrier, made of cotton and polyester, with plastic buckles. - Color: Navy - Model Name: ZERO - Material: Cotton/Polyester - Buckle Type: Plastic Buckle Thank you for viewing. This baby carrier can be used from 14 days old to 1 year old! It's a rare type that can be used without an inner pad, and it was very useful for us until around 3 months old (*^^*) There are no noticeable stains, but it has been used daily, so it has a corresponding amount of wear. The stain in the second picture might come out with washing. The retail price is approximately 15,000 yen. I am also selling on other sites, so please check for stock availability in the comments if you wish to purchase m(_ _)m
