Collaborative Design
ION-Sei was born out of a synthesis of Japanese philosophy and German product design.
Holistic Design Philosophy
ION-Sei’s designers were inspired to make an attractive, easy-to-use toothbrush with a long-lasting battery life.
Our teeth work daily to process the fuel we need to live. The mouth is used to form our words; it is the seat of communication.
Give yourself and your loved ones the gift of a supportive, holistic oral care system.
Technology Meets Traditional Craftsmanship
ION-Sei combines the latest in oral care technology with a tradition of great craftsmanship.
ION-Sei: Your Electric Conductor Handle
Carefully-designed ridges on the handle ensure a firm grasp. The panel on the back of the electric conductor handle generates a stimulating, gentle electric charge.
Transparent Brush Head
Specifically designed to allow the photocatalysis reaction required for ionic cleaning.
