Valve Action marker for industrial graphics with liquid quick-drying paint. It is a metal round body with a felt double-sided replaceable tip and a cap with a clamp. It is intended for almost any surface and provides long-term stable marking to atmospheric influences. The lack of xylene in the paint composition reduces the risk to the health of users. The color palette, consisting of 18 bright, including fluorescent colors, allows you to make well-marked inscriptions, even on dark surfaces. The Valve Action marker can be used as a universal marker, for example when marking on metal, glass, wood, concrete and plastic.
