I buy these in bulk - here is why: When you are out shopping, having lunch, running errands, or just out in the backyard, and your baby drops the pacifier the last thing you want them to do is to put it back in their mouth with all those nasty germs on it. So having these will solve that problem. They are food grade, so they are safe for baby's, and they smell pretty good too. I keep one in the car, one in the diaper bag, one in the stroller and a few in the house. Because you never know when a pacifier will drop - and they drop all the time!
