ABZ fasteners are a convenient and safe way to fasten cloth diapers.  As easy as ABZ.  They are suitable for all sizes of diapers from preemie to adult.  Our leading-edge design includes a comfort contour edge for fastening and rounded edges on the back for the safest and most comfortable fit. Available in 3 colors. Once the diaper is in place, use the teeth to hook the fabric on the outside and pull towards the middle using the teeth to hook the fabric towards the middle-front of the diaper.  When secure you should still be able to slip a finger beneath it. It is quick and as easy as ABZ. To prevent snags and extend the life of the diapers, always stretch the fastener to release the teeth from the fabric. Do not pull straight up or yank the fastener out of the fabric. SIZE: 3x1 inch or 7.6x2.5 cm
