The Tsubu-Tsubu 2000 Hot by Dot is one fantastic product. Perhaps most notably, it is made of polyethylene--a material that becomes more flexible when in contact with heat. Oil-based lubricants are safe to use with this condom and it is a great alternative to those who are allergic to latex. And yet it still provides the durability and safety that one expects from a latex condom. Studded and featuring a lubricant that has heat-producing qualities, the experience is kicked up a notch! The overall shape of this pink condom is mildly flared towards the head, providing a comfortable fit. This is a unique product from Okamoto.
