A typical pen applicator includes a tubular body in which a liquid absorbing material is disposed to hold the hazardous solution. A tip is in contact with the reservoir and one end of the tip acts as a wick to draw the solution from the reservoir to the tip, and the other end of the tip is configured to apply the solution to a surface when that end of the tip is placed in contact with the surface. A tip cover is provided to seal the tip and tip-end of the tubular body prevent inadvertent application of the solution and to preserve the shelf life. A cap or sealing member is provided at the end of the body to seal the reservoir.
