The Molotow ONE4ALL Twin 1.5 to 4 mm Acrylic Marker in Stone Grey Dark is a versatile tool designed for maximum flexibility thanks to its dual-tip system. It allows easy switching between fine detail work and broader strokes, featuring a 1.5 mm fine tip and a 4 mm broad tip. Its deep dark grey tone delivers strong contrast and intensity, ideal for shading, bold outlines, and graphic compositions. Formulated with acrylic-based paint, it provides a satin finish, high opacity, and a permanent result after fast drying. Designed for intensive creative use, this marker is refillable and features replaceable nibs. It can be diluted with water or acetone depending on the desired effect and is fully compatible with the ONE4ALL range as well as the brand’s acrylic sprays, ensuring consistent colour integration across techniques. Thanks to the patented FLOWMASTER capillary system, it ensures smooth and even paint flow. It adheres to almost all surfaces (subject to compatibility), making it a reliable tool for artists, illustrators, and creators.
