This particular type of material is phthalate-free and non-porous. It can easily be used with both water and oil based lubricant. Velvet Cote is also an excellent conductor of vibrations. This is why it’s so often used to manufacture rabbit and penis vibrators.
As far as cleaning, it is recommended not to boil any item made from Velvet Cote. However, it is quite easy to clean and disinfect. Just wipe it down with isopropyl alcohol or simply wash it under warm water and anti-bacterial soap.
