The Molotow ONE4ALL 4 mm Marker in Stone Grey Dark is a highly opaque acrylic marker designed for precise and consistent application across a wide range of surfaces. Its deep dark grey tone enables strong contrasts, sharp details, and dense fills, making it suitable for both artistic projects and creative customisation work. 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 ideal for customising objects such as sneakers, instruments, or creative accessories, offering strong freedom of expression. The ONE4ALL system is built with sustainability in mind thanks to its refillable design. The paint can be diluted with water or acetone depending on the desired effect, allowing greater control over flow and application. Non-toxic and reliable, this marker is suitable for frequent and varied creative use.
