About ION-Sei: Continuing a legacy of fine Japanese craftsmanship, ION-Sei was founded by Sanyei in Japan to revolutionize oral care, enabling professional, high-quality teeth cleaning at home. Our Challenge: Answering the call to create a toothbrush for a new generation, Japanese and German designers were brought together to collaborate and produce ION-Sei for Sanyei. ION-Sei’s team is dedicated to providing the best oral care available, offering patented, innovative ionic technology directly into the hands of consumers. Sanyei’s design-led creations inspire people to enjoy life more and experience Japanese-style comfort. Packaged within a sleek and simple wand, the toothbrush is a pleasure to use and valuable addition to your personal care routine and that of your loved ones too. How Does ION-Sei Works: In a photocatalytic effect, UV light hits our patented TiO2bar, producing electrons that travel further and deeper against plaque and bacteria. Through the weak electrical current, the opposite to your body’s natural charge, bacteria causing plaque are attracted to the head, while specially designed spiral bristles make both easier to remove. You can be more gentle on gums, and still affect plaque in your mouth. You’ll experience smoother, cleaner feeling teeth over time. And can expect a healthier mouth with less risk of cavities. ION-Sei three USPs: Joyful brushing With our innovative brush head, designed in Japan, normal spiral bristles are combined with tapered ones that are softer for your mouth. The gentle-on-gums 31,000 strokes-per-minute sonic vibrations give you deep yet gentle cleaning power. Simple water, more natural Electrons generated travel through simple water and saliva onto your teeth. No toothpaste is needed unless you want to use it. Well-travelled toothbrush Lightweight and travel-friendly—simply charge ION-Sei with a USB adapter. It is lightweight and easy to carry anywhere.
