RFSU condoms are made from natural rubber latex, a regrowing raw material that's even recyclable! During the latex production in the plantations in Malaysia, ecological sustainability is a matter of course. Careful washing processes make the latex as hypoallergenic as possible. The entire quality control is made with physical processes, i.e. without animal testing! The outer packaging is printed with non-toxic inks. Conclusion: RFSU are excellent condoms, also for environmentalists.
