A special technical feature is the Flowmaster™ pump-valve that guarantees a controlled paint-flow. The more pressure is imposed on the valve the more paint can flow. This feature allows best writing performance on almost every surface. The mixing balls inside the marker make sure that the highly concentrated pigments are evenly distributed within the paint for optimal writing results. Therefore it is recommended to shake your marker well before use.
The highly pigmented, acrylic-based hybrid-paint is easily mixable with other ONE4ALL colors (for individual shading), it can be diluted with water (for translucent effects) or with acetone (for permanency on fatty surfaces). It works on almost every surface, is silk-matt, quick-drying, has an incredible opacity and is absolutely UV-resistant.
