This is an evolved version of the onbuhimo (baby carrier) from Lucky Industry. I've only used it a few times indoors. After that, I was able to carry my baby on my back with a different carrier, so I stored this one in its box. This carrier is very easy to use and has a head support board, so the baby's neck won't slump even if they fall asleep. It's hardly been used, so there are no stains or signs of wear. The photos are of everything included, including the instructions. Suitable age: From when the baby's neck is stable (around 4 months old) to 24 months (13kg) Designed with a wide crotch. 3D mesh to release heat Wide shoulder pads Please understand that this is a used item before purchasing.
