Silicone toys are higher-end toys because of the smooth, non-porous, long-lasting silicone material from which they are made. Silicone toys are an excellent choice for anyone with a rubber or latex allergy. Silicone toys are a great investment because they can be sterilized by boiling or running through the dishwasher and ideally will last a lifetime! (REMEMBER: Never use silicone-based lubricants with a silicone toy, it will erode it!)Glass Products: If you're looking for another great material that will last a lifetime and is super hygienic, try glass!
