A mask that combines design, function, and practicality T-MASK 03 . Based on the shape of T MASK 01 , it has a minimalist design that minimizes the contact area with the face and boldly exposes the cheeks from the eyes. Among the 3-layer filters, the nanofiber filter, which catches more than 99% of 100 -nanometer particles, was invented by Professor Emeritus of Tokyo Institute of Technology. Fewer joints between the ear straps and the mask body reduce the feeling of tightness on the face, realizing a light and comfortable fit.
