Beyond Seven condoms are made of Super Thin Sheerlon, an advanced material so strong and durable, it can be made much thinner than an ordinary latex rubber condom. Sheerlon has a silkier, more natural feel, much like skin itself. World famous Beyond Seven condoms are manufactured by Okamoto, the same makers as Crown condoms. Each condom has been tested electronically to guarantee reliability. All condoms expire 2-5 years from date of purchase.
