The Molotow ONE4ALL 4 mm Marker in Mustard Yellow is a highly opaque acrylic marker designed for precise and consistent application across a wide range of surfaces. Its warm, slightly vintage mustard yellow tone allows for rich contrasts, bold accents, and expressive compositions with natural character. Formulated with water-based acrylic paint, it delivers excellent coverage and fast drying performance. Its semi-gloss finish provides a clean, professional look, while UV resistance helps maintain colour intensity over time, both indoors and outdoors. Highly versatile, it adheres reliably to many surfaces including canvas, wood, metal, plastic, and textiles. It is also well suited for customising objects such as sneakers, accessories, and various creative surfaces, offering strong flexibility in use. The ONE4ALL system is built around a durable refillable design. The paint can be diluted with water or acetone depending on the desired effect, allowing control over flow and application. Non-toxic and reliable, this marker integrates easily into regular creative practice.
