We offer what I believe is the only really safe, convenient, effective design of straw hole mask available.

Our straw hole masks have a convenient velcro flap that lifts up to open a 3/8” (10mm) marine-grade pure brass grommet hole. When the flap is closed, a precision laser-cut, food-grade silicone rubber plug automatically centers itself in the grommet, completely blocking air flow through the hole.
