Last year, I wrote about Guangzhou Daming United Rubber Products claiming the title of the World's Thinnest Condom And just shortly before that, I wrote about Sagami taking the title from one of our favorite brands, Okamoto. But now, legal trouble is on the horizon, and who's to say what is truly the world's thinnest condom?

Once again, it all comes down to materials. The Sagami condom is made of polyurethane, which enables it to come in at 0.01 millimeters thick, because polyurethane can be made much, much thinner than latex without having breakage problems.

But never mind polyurethane. Okamoto claims that their latex 0.038 mm, called the Okamoto Platinum 0.03, condom is still the thinnest latex condom in the world, which the Chinese company is contesting with their lawsuit.

But they aren’t suing for money. United Rubber Products is only requesting the monetary compensation of a single yuan. Their real request is that Okamoto take the labeling off of their package. And the Guinness Book of World Records verified the big win for the Aoni condom.

You see, Okamoto claimed that a third party had evaluated the United Rubber Products condom, called the Aoni, and found that it was not the .0036 millimeters it claimed. Therefore, they claim that they have the right to keep the, "World's Thinnest Condom," label on their super-thin products.

As with other super-thin condoms, the Aoni is known for its super stretch appeal, as demonstrated in the photo above. But this matter isn't a stretch--especially for markets in Japan, where Okamoto is from, and China, where the Guangzhou Daming United Rubber Products company is based. Having two condoms with the same label automatically makes both of them wrong in the eyes of the consumer.

The lawsuit was reportedly filed in September of last year, but only recently has Okamoto acknowledged it.

You may be asking yourself why such a teeny, tiny fraction of a millimeter matters? Why compete for such extreme thinness? For most people, the thickness of a condom equates to how close it feels to wearing nothing at all. The thinner it is, the more likely you'll be able to feel your partner's warmth and body.

It's good to see that both companies are so willing to verify that they products meet the consumer's standards of sensitivity. But how long does this battle go on for before the world's thinnest condom is simply no longer practical or safe?

As such, none of these three world's thinnest condom contenders are currently FDA-approved, which means that none of them can be sold in the United States or by companies based in the US. The thinnest condom Condom Depot carries? The Okamoto 0.04. As always, just make sure it's the right size for you before taking the plunge.
