I've flame-tested Tantus dildos and all passed with (as suspected) flying colors.
I just flame tested the holder for the Bedroom Kandi "Hold on to me" vag balls. It caught fire, and when I wiped away the soot I also wiped away material. It flaked off AND was sticky / soft.
The founder of OhMiBod is telling me, however, that the flame test is too hot and isn't valid and that he's being told this by testers and manufacturers.
