Molotow One4All markers are permanent acrylic-based markers. Suitable for both indoor and outdoor use, they are engineered and manufactured in Germany (except for the four fluorescent colours). They feature a patented capillary system and a Flowmaster valve which offers a consistent paint flow to the tip of the marker. The One4All range includes 50 colours, all of which are permanent, UV-resistant, quick-drying and non-toxic. The acrylic ink used in these markers is dilutable with water or acetone (to 1-3%), and will dry quickly to an opaque, semi-gloss finish on nearly any porous or non-porous surface. These Molotow One4All Acrylic Twin markers have two replaceable tips: a 1.5mm pointed crossover tip and a 4mm bullet tip for bolder work. This set includes twelve One4All Acrylic Twin Markers. These markers can be used with any other Molotow spray paints and markers. Each marker can each be refilled at least 50 times using Molotow One4All Paint Refills (which can be mixed to create the colour of your choice).
