GumDrop rests comfortably against your baby’s delicate skin, offering a silicon-covered, curved surface and a familiar nipple shape that babies love. Special, Uni-Body Construction Won’t Fold or Come Apart GumDrop’s uni-body construction means that the pacifier can’t be disassembled and won’t come apart. Its unique design involves a plastic guard that is completely over-molded with medical grade silicone. So GumDrop’s surfaces are as soft as the nipple itself. In addition, GumDrop’s open back lets you easily position and reposition the pacifier in the baby’s mouth.
