An empty marker that can be filled (and refilled) with Molotow One4All paint refills, fluid acrylic paints, watercolours, inks and dyes. It has a 1 mm brush tip, which means it handles like a brush, but has the flow of a pump marker, so that you have consistent colour and thickness throughout any piece of work. The nib is interchangeable so you can easily replace it, or change from a brush tip to an alternative pen tip if you want to produce a different effect. Compatible with the following tips : 4 mm round, 4 mm high-flow, 2 to 5 mm calligraphy, 2 mm chisel and 1 mm specialtech exchange tip. The Molotow One4All range is adaptable and environmentally friendly, as all markers are reusable and both the markers and the spray paints use the smallest amount of solvents possible, relying on an acrylic paint which is 85% water. The packaging is environmentally friendly and the manufacturer has a social responsibility program.
