Adult devices for sexual and therapeutic purposes are typically developed and marketed into a limited number of developed countries with high disposable incomes. However, these represent a fraction of the total potential adult population and accordingly it would be beneficial in all of these markets to offer low cost, ideally very low cost, but effective devices. Solutions meeting this very low cost manufacturing requirement as well as offering new concepts such as limited use or disposable devices are presented exploiting blow molding techniques. Further, many potential markets present issues not prevalent in historical markets that may make it difficult for individuals to acquire devices, even without the financial issues, and hence solutions are presented wherein adult devices can be acquired and/or marketed in manners that address or mitigate these issues.
