Made from stretchable non-toxic and colourful material, the Snappi – or Nappi Nippa in British English is designed in a T-shaped with grips on each end. These grips imbed in the diaper fabric to ensure a snug-fitting diaper without the worry or hassle of pins.
The Snappi diaper fastener is faster and safer to use than safety pins, providing a practical and reliable way to fasten a cloth diaper replacing traditional diaper pins. The Snappi diaper fastener works best with cotton prefolds and terry diapers, but might be more difficult to hook into tighter woven diapers such as flannel or hemp diapers for instance.

To fasten the diaper, the Snappi is hooked in the diaper on the left, stretched and hooked on the right, stretched down and hooked in the middle so as to form a Y shape. By doing this, the Snappi should be secure, the diaper will fit snugly and the baby should not be able to undo it. The diaper cover is placed over the diaper and the Snappi fastener.

The Snappi diaper fastener can be hand-cleaned with soap and hot water. It should not be machine-washed together with diapers as this may weaken the grip attachment.

For more safety, inspect your Snappi before each use and discontinue using immediately if the teeth or any other parts shows a sign of cracking, tearing, breakage or wear.
