"Snappi® gives a modern touch to baby care and will always be in demand as long as babies are born. It is made from a stretchable non-toxic material which is T-shaped with grips on each end. These grips inbed in the diaper fabric to ensure a snug-fitting diaper with enough natural movement for the baby. Snappi® is available in a range of bright and pastel colours."
