I purchased this last year on Mercari. I was looking for a carrier around the time my child started getting heavier, around 3 months old, and I was debating between this and the Mini. The Mini seemed like it wouldn't be usable for long because it would be hard on the shoulders, so I bought this one. This carrier has a waist belt and was useful up to 15 months. Please search for "BabyBjorn Move" for the detailed specifications. Since it was originally used, it does show signs of wear and tear^^; There are no noticeable stains, but it has some fraying and other signs of age. I have the box, but it's difficult for me to prepare a separate cardboard box, so I will wrap it in plastic for shipping. I don't have time to wrap it carefully, so it will be like the picture. If you don't mind, please feel free to purchase it. I don't have any plans to lower the price at the moment.
