Trojan Ultra Ribbed Spermicidal Condoms (12 Pack) For those who are serious about birth control & still want intense pleasure; what is better than a standard condom? Seriously; it is the Trojan Ultra-Ribbed Spermicidal Condom! It is identical to its cousin ultra-ribbed; but this one has Nonoxynol-9 spermicide for extra protection against pregnancy. Plus the condom also has a reservoir end for extra safety. This condom is designed to give the man more intense pleasure as well. The head of the condom is wider than the base & shaft. This gives more room for friction as the penis moves in & out. Advocates of this particular condom say the sensation is extraordinary. Adding the great feeling with the sense of protection & this condom goes into the win column.
