Specially selected ultra-fine condoms from all over the world. Generally, condoms that are thinner than a human hair (0.06mm) will be categorised as a thin-type condom. The thinnest latex condom is around 0.036mm, but even thinner condoms can be made using polyurethane (PU). Today, the thinnest PU condom is 0.018mm.
Don't be mistaken in thinking that thinner condoms are easier to break though. The strength of PU is 3 times stronger than latex so it gives you better protection without giving up an even better sensation.
