In the Land of the Rising Sun the work of swimming pools was resumed from June 1. This means that there was a need for a special protective mask that would not fall in the water and would not get wet, but at the same time protect against the possibility of infection. For example, people swimming on the same track, or children to whom the coach gives instructions, standing on the board, and the distance between them is less than 1, 5 meters.
A small Tokyo company developed and started producing such masks. They are made of transparent material, do not slip in the water, even if you actively move, and do not hinder speech. Protective accessories are already in great demand, the company received more than 16 thousand orders.
