The expensive price can be explained by the production process. The thinner condoms should be, the slower they will rule extracted from the polymer solution resulting in very thin condoms. Here adhesion forces take care of the thin polymer film.
Thus, the manufacturing process of a super thin Kondomes like this almost 3 times as long as needs a normal condom.
Too bad that these condoms are not the piece can be had anyway for the price below 50 cents. Or are there cheaper alternatives?
Conclusion:
Those looking thin condoms for the next most perfect "without" emotion. Is hereby very well served.
