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.

Electrocardiogram taken with Einthoven's original string galvanometer, 1903. In 1901, Einthoven completed a series of prototypes of a string galvanometer. This device used a very thin filament of conductive wire passing between very strong electromagnets. When a current passed through the filament, the electromagnetic field would cause the string to move. A light shining on the string would cast a shadow on a moving roll of photographic paper, forming a continuous curve showing the movement of the string. His assignment of the letters P, Q, R, S and T to the various deflections is still used. The term "Einthoven's triangle" is named for him. It refers to the imaginary inverted equilateral triangle centered on the chest and the points being the standard leads on the arms and leg. After his development of the string galvanometer, Einthoven went on to describe the electrocardiographic features of a number of cardiovascular disorders. Einthoven received the Nobel Prize in Medicine in 1924.
