Unlike other retainer cases, Selfie retainer Case can be boiled or microwaved without damaging the high-quality medcal grade silicone, which kills bacteria and viruses that usually live on other retainer cases. Just make sure not to leave your retainers inside when you are sterilising the case! Overall, it is easy to use, soft to touch and looks great!
