The Molotow ONE4ALL Twin 1.5 to 4 mm Acrylic Marker in Signal Yellow is a versatile tool designed for maximum creative freedom thanks to its dual-tip system. It allows easy switching between fine lines and broader fills, featuring a 1.5 mm tip for detailing and a 4 mm tip for larger areas. Its bright, high-visibility signal yellow tone delivers strong visual impact, ideal for bold accents, sharp contrasts, and dynamic 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 perfect colour and technique consistency. 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.
