Found this review for the Sagami Condoms...
These condoms are 0.02mm thin, so thin it feels close to nothing. When I first saw this, it was in Hong Kong and the packaging is so unique. Instead of the tear open package that most condoms come in, this one come in a plastic container, similar to opening a contact lens container. This makes it stand out and feel a little more classy compared to the other brands.
Got my hands on the Sagami Original, these sheer thin condoms are a sheer pleasure to use, the material is a little tougher than a latex condom, it's good cause you know you're well protected from breakage. It may seem a little tough but when it slips in, it feels comfortable and when you have contact with your partner, you can feel all the heat that your girl emits, unlike latex when sometimes you lose the heat factor when making out.
Because this condom does not "stick" to you skin like a latex condom, there is more slide, making insertion easy because it is more slick when lubed up. Also you do not have the feeling of latex "gripping" your manhood before penetration, allowing you to feel your lover's tightness during insertion and also when she gets orgasms, you can feel all the action going on in her love hole.
