iroha temari is a series of powerful, streamlined vibrators. The product can be operated by a single button and offers four vibration strengths and two pulse patterns, but its key feature is the base, which is segregated from the round patterned top portion. This makes it possible that the vibrations stay focussed and are not directly transmitted to the hand. The smooth silicone coating is dust-repellent, the whole device is waterproof and can be recharged via a USB cable.
