EZ Inspector Kit with One Marker

Inspector Kit includes handheld UV light and one invisible ink pen for hard surfaces. Used by housekeeping supervisors to make sure an area has been cleaned. When an area is clean, the supervisor writes the date on an area in the special invisible ink. After the area is supposed to have been cleaned, the supervisor goes back with the special light and if the date is still there, the area has not been cleaned, if the date is gone, the area has been cleaned. Invisible ink is water and detergent soluble. Batteries not included with lamp.
