Product details

  1. The double-layered mask interior uses “tea seed oil fiber”. This hygienic solution suppresses bacteria growth and cleanses the area inside the mask to prevent odors from forming even after extended use
  2. The mask fits comfortably across the contours of the face, making it easier to breathe, while tea seed oil is used to enhance the moisture retaining properties of the mask.
  3. The length of the ear straps can be adjusted to prevent ear strain.
  4. The mask is washable and reusable. Retains the same antibacterial effect even after 20 washes.

An environmentally-friendly sustainable mask.

With the aging of farmers producing tea, more and more tea plantations in Japan’s tea-producing areas are being left untended. The increase in abandoned tea plantations brings with it the very real risk that scenes of Japan’s traditional tea plantations will be lost to time. We view these abandoned tea plantations as a precious resource, and have worked with producers and welfare facilities to establish a system for gathering and processing a stable supply of tea seeds. Our latest use of tea seed oil is in a face mask.

Not only is this reusable mask environmentally friendly, it is also expected to help counter the abandoning of tea plantations by providing tea farmers with an additional source of revenue through the purchase of tea seeds in the same price range as tea leaves.
