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 one has a waist belt and was useful up to 15 months. Please search for "BabyBjörn Move" for the detailed specifications. It was originally a used item, so it does show its age a bit^^; There aren't any noticeable stains, but there's some fraying and other signs of wear and tear. 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 photos. If you don't mind, please feel free to purchase. I don't have any plans to lower the price at the moment.
