Cheaper sex dolls are inflatable, using air. These dolls, representing the lowest price-range (less than US $75), are usually made of welded vinyl and bear only a passing resemblance to actual people. They have an artificial and typically crudely designed vagina or penis, but due to their affordability many users are willing to overlook their shortcomings. They often burst at the seams after a few uses, although they are commonly given as gag gifts and therefore many may not be used at all. In Russia for some years the Bubble Baba Challenge humorously featured participants river rafting on blowup dolls as a matter of entertainment but in 2013 the race was cancelled on "health and safety" grounds.
One of the most important features of a sex doll is the construction. The material used (rubber, fabric, TPE, or Silicone) dictates not only the cost of the product, but also the purpose. Whether you're thinking about getting a sex doll yourself or are just curious about what folks see in an inflatable partner, there is certainly a great deal of perks to sex doll ownership.
In Japan, sex dolls are known as "Dutch wives" (ダッチワイフ datchi waifu), which now refers to relatively inexpensive dolls. Their name originates from the term, possibly English, for the thick rattan or bamboo bolster, used to aid sleep in humid countries by keeping one's limbs lifted above sweaty sheets. Orient Industry is considered to be the leading manufacturer of high-end silicone dolls in Japan, which started using another term "love dolls" (ラブドール rabu dōru) around 1998 to distinguish their dolls from the image of inflatable dolls associated with the term "Dutch wife". The term has stuck and is now used generally to refer to any high-end product. There is a business, Doru no Mori (Doll Forest) in Tokyo, that rents love dolls and rooms to male customers. In March 2007 the Japanese daily Mainichi Shimbun newspaper reported that there are also rental businesses that bring the dolls to the customer's home, and that the specialist love-doll magazine i-doloid has a print-run of 10,000 copies per issue.
Now, TPE stands for thermoplastic elastomer, which is essentially a mixture of polyvinyl chloride and silicone. This is a type of skin that is very soft, and it mimics the feeling of human skin. TPE is way more realistic in feeling and it definitely mimics the feeling of human skin. It also is much cheaper than silicone alternatives, sometimes even hundreds of dollars cheaper. TPE also allows you to move the doll around in various ways, since it has more flexibility. TPE dolls don’t really need to be bathed, but you can, just be mindful of the water. It also is hypoallergenic as well.
