Collaborative Design

ION-Sei was born out of a synthesis of Japanese philosophy and German product design.

Holistic Design Philosophy

Design Studio aroma ID, Offenbach am Main, Germany

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."

Steffen, Designer
