Falsely advertised as silicone, Buyer Beware
As soon as I opened these I could smell that they had been falsely advertised as medical grade silicone. I went to the website listed on the package "topcosales". Sure enough they say nothing about medical grade silicone. Instead they are listed as SensaFirm™. They smell very chemically. Definitely not silicone. Upon googling sensafirm it's described as "SensaFirm is a trademarked name for a line of products made of a soft variation of thermal plastic elastomer, a mixture of polyvinyl chloride and silicone. TPE is a polymer that has many uses, one being sex toys.".  No wonder it stinks.  These were a gift and I'm going to have my friend who purchased them seek a refund from amazon. I don't feel comfortable using something that cannot be fully sterilized like silicone, glass or metal. It's frustrating and disappointing that these aren't as described.
