Swaddle Up Original NB For 2.2kg ~ 3.8kg (4.8 lbs ~ 8.4 lbs) Used a few times while my child was a newborn. Since my child didn't wake up due to the Moro reflex, it wasn't used very often. There are no visible stains or malfunctions that would hinder use. It's in good condition, but since it's a used item, please refrain from purchasing if you are concerned.
