Nappi Nippa (single)

This ingenious device looks feindish to use but simply hook left, then right and then centre. It grips onto the loops of towelling but doesn't go through the fabric making it totally safe for baby.  

Nappi Nippas are the way forward for fastening all types of fabric washable nappies, faster and safer than nappy pins.

Toddlers simply can't get them off and they flex as baby moves.
