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.

James Prescott Joule (December 24, 1818 - October 11, 1889) was an English physicist and brewer. He studied the nature of heat, and discovered its relationship to mechanical work. This led to the theory of conservation of energy, which led to the development of the first law of thermodynamics. He worked with Lord Kelvin to develop the absolute scale of temperature, made observations on magnetostriction, and found the relationship between the current through resistance and the heat dissipated, now called Joule's law. He showed that energy is conserved in electrical circuits involving current flow, thermal heating, and chemical transformations. The SI (thermal energy) derived unit of energy, the joule, is named after him. He died in 1889 at the age of 70. His gravestone is inscribed with the number "772.55", his climacteric 1878 measurement of the mechanical equivalent of heat, in which he found that this amount of foot-pounds of work must be expended at sea level to raise the temperatur...
