PITTA MASK is a mask brand of ARUX Corporation, a Nagoya-based company established in 1853 that manufactures and sells general medical supplies. The PITTA MASK mask series, which won the 2014 Good Design Award, is made of soft and flexible polyurethane, so it does not cause ear discomfort when worn for long periods, and it fits closely to the contours of the face while providing excellent breathability.
