Ergobaby Baby Carrier Infant Insert Includes instruction manual and box. Can be used from birth until around 4 months old when the neck is stable. It was stored at home without being used much, so I think the condition is clean. This is a used item stored at home, so please refrain from purchasing if you are looking for perfection. Only those who understand are welcome. Please check the condition in the photos. It will be shipped by courier service in the box. If you don't need the box, I can lower the price a little.
