There a lot of different types of platinum silicone though...not all are ok to be inserted into the body. That's why there are different grades of platinum silicone...I found this information:
Types of platinum silicones: Industrial grade, prosthetic grade, food grade, medical grade, and implant grade. From what I read, the first is not to be used on the skin...its for mold making. Prosthetic grade is perfectly safe for skin contact, but not ok for use inside the body for extended periods of time (use a condom). Food grade and medical (healthcare) grade are safe for penetration. Implant grade is used for making stuff that stays inside the body, like breast implants, etc.
Something tells me that maybe he isn't familiar with this information since he is new to this business...
