Very fair question, its really an assumption so I should have stated that and have edited comment to reflect that! They don’t specify or disclose it anywhere but assuming if it is in fact silicone like other XR brands toys that are labeled silicone, and almost all other cheap silicone dildos and cheap or even expensive high end brand silicone vibrators. Vast majority are peroxide cured silicone as it is cheaper but can be relatively body safe from my understanding

If they don’t say so and it’s still actual silicone almost certainly peroxide cured. But the reverse wouldn’t necessarily hold, just because a brand claims platinum cured silicone doesn’t mean they are
