Chuchu DentiStar pacifiers, designed to be less likely to cause buck teeth. Set includes glow-in-the-dark star pattern purple and Miffy orange. Used 2-3 times. My baby didn't like them at all, so I tried putting them in their mouth a few times, but they were immediately spat out. Each use was only for 1-2 seconds, so they were hardly used. They were sterilized with Milton and stored. The purple one has a slightly white appearance at the base, as if some force was applied. (See photo) It seems to be fine for use.
