Product Details
The Center for Disease Control has recommended the use of cloth face masks to help fight the spread of COVID-19.
This face mask is made from 100% polyester and includes two ear loops with adjustable grommets for a comfortable fit.
The printed area of the mask is approximately 7" wide by 5" tall. This mask fits well on adult mens' faces without the grommets but, due to the adjustable grommets, can be worn snuggly by adult women, as well.
Please note - this is NOT a surgical grade mask. It is not intended for any medical or commercial uses, whatsoever. It is a simple, cloth mask designed for everyday use to cover your mouth when out in public. The mask should not be used in any medical or surgical setting.
We make no warranties that the mask prevents infections or the transmission of viruses or diseases.

Joseph Ludwig Franz Ressel (June 29, 1793 - October 9, 1857) was an Austrian-Czech forester and inventor who designed one of the first working ship's propellers. He worked for the Austrian government as a forester to secure a supply of quality wood for the Navy. He began testing his ship propellers for the first time. He was awarded a propeller patent in 1827. In 1829 he modified a steam-powered boat and test drove it in the Trieste harbor at six knots before the steam conduits exploded. The police banned further testing. The explosion was not caused by the tested propeller as many believed at the time. Among other his inventions are pneumatic post and ball and cylinder bearings. He was granted numerous patents during his life. He died in 1857 at the age of 64. A monument to him in a park in Vienna commemorates him as "the one and only inventor of the screw propeller and steam shipping".
