Used a few times when discharged from the hospital and during the newborn period. I received another one from the same brand and started using that, so I'm selling this one while it's still in good condition. You just put the baby inside and hang it on your shoulder, so you can put it on quickly and easily when the baby cries. It folds up compactly when not in use, making it convenient to carry around. The baby fits snugly against the curves of the body, and seems to feel secure, as they would sleep soundly while using it. * Instruction manual and box (with some tears) included * Original price was around 8,000 yen * There are no stains or dirt, and it's in very clean condition overall, but please note that this is a personal inspection, so there may be some oversights. * The box will be folded and packed, and shipped via Yu-Packet Post. Please understand this before purchasing.
