Also looks used. Teeth marks in tray
It looks used after looking closer. There are teeth marks in one of my trays. View photo. This has some kind of powder or film on it that burned my tongue and lips. I washed one of my trays before shaping it because  I noticed the film. Upon shaping it, it burned my lips and gums and not because it was hot. So of course I licked the one I hadn’t molded in the hot water and it burned my tongue where it touched. Also interestingly enough the other one star review is not viewable
