Description
Valve Action marker with liquid quick-drying paint. The invisible paint glows bright blue when viewed under an ultraviolet lamp, and is resistant to weather changes. The inscription is applied in the same way as any other marker or marker. Before applying the concealed inscription, it must be ensured that the surface is cleaned of mechanical impurities. For effective use, marking with an ultraviolet marker should be applied in hidden places. Ideal for security, quality control, unauthorized access and anti-counterfeiting. The metal body of the marker and the double-sided replaceable felt tip allow the marker to be used in industrial conditions for a long time.
