alcohol pre-injection swabs are low cost high quality swabs, generally
used above the intended injection site prior to injection, so as to
reduce the bacterial load on the skin. Alcohol after getting partially

area dry out naturally. These swabs are properly sealed in air tight
boxes to prevent evaporation of alcohol.
