The material is called TPE which is also known as TPR. It's safety number is only 6 out of 10 but it is better than 5 right? The basic explanation of this material is... A rubber polymer blend or compound that exhibits a thermoplastic character. TPR has an excellent flexural fatigue resistance and high impact strength. It starts out soft and has products added to make them harder. This type of material is ideal for manufacturing a variety of textures. It does have a wavy texture to it due to the ripples it has on the inside. It feels wonderful though.
The best way to describe the shape of it is to compare it to a baby's sock. I know that doesn't sound right but that's basically what it looks like. I wouldn't suggest thinking about that when you try it though. You might not be able to use it afterwards. It's nice and smooth on the outside and it has little, soft waves on the inside which stimulate a lot and feels really good. Especially if you have a cock ring on and what to have a longer experience with it. The size is also not super huge but it is very strechy and will fit almost anyone. The only reason why I say it won't be good for the above average is because the thicker you are, the less it covers. Since it is small and flexible, it is easy to store and travel with. It doesn't look like much when you first look at it until you really stare for a while. So even if you pull it out, you might not have a problem. As long as you are not using it in the open public ha ha.
Though it cannot be boiled, it can be washed in mild soap, warm water, or toy cleaner that you can purchase right here on the website. I usually use warm water but when it gets to the point that it really needs to be cleaned, I usually go for the mild soap. But on occasion I have purchased the toy cleaners and they have worked pretty well.
My experience with this product was amazing. I use it when ever and where ever I feel that urge. I would recommend this product to anyone looking to get a quick pleasure in here and there. I love it.
