Are colored cups safe?

The dye used in Lunette menstrual cups is FDA approved for medical and food use

Yes. The dye used in Lunette menstrual cups is FDA approved for medical and food use. The colors don’t contain heavy metals or phthalates. We don’t use really bright colors or glitter in our products- we choose our colors very carefully so they are truly safe to use inside the vagina. Plus the type of dye used in the Lunette menstrual cups are inside the silicone so it’s not possible for the color to leach like with some cheaper dyes which are also used in other menstrual cups.
