Tantus again has proved its ingenuity with the O2 Revolution line, available in both feminine and masculine colors. The Pure Skin outer layer is soft but not tacky. The inner Muscle Core is firm but pliable. That combination alone is enough to make us thankful, but that’s hardly the end. Unlike other silicone-only companies, Tantus is among the very few that back it up with 100-percent platinum silicone that’s boilable, bleachable, dishwasher-safe, and taste- and odor-free. Trust us when we say those are features your customers will truly appreciate.
