I rinsed it lightly, but it's never been used for diving. This color is a limited edition sold only to instructors, and isn't even listed on the manufacturer's website. If you're looking for this color, it's first come, first served! This is the TUSA Paragon S diving mask, featuring a 3-layer tough frame and UV-cut mirror lenses. Manufacturer's suggested retail price: 25,300 yen Thank you for looking.
