RFSU is a premium line of luxury condoms imported from Sweden. Mamba (now named TIGHT) features a snugger, more tailored condom for a wonderfully close fit. Its contoured pleasure shape adds to sensation. RFSU condoms are made of the highest quality latex, silicone lubricated and certified vegan. Their natural latex is durable, yet maintains a soft and silky feel. RFSU exceeds international condom safety standards.
