Arrtx double-sided marker pens Oros — 12 earth-tone colours, dual-tip markers

Arrtx Oros double-sided marker pens set includes 12 earth-tone colours designed for drawing, sketching and colouring. Each marker is dual-tip with a broad chisel tip and a fine tip, providing versatile line widths for illustration, rendering and detail work. The set comes in a storage box with individual compartments for each marker; the box lid folds out to act as a stand and the empty box can be reused for storage. Markers are alcohol-based for smooth blending, vivid pigmentation and fast drying.

Advantages

High pigmentation ensures rich, bright earth tones that retain intensity during blending. Alcohol-based ink blends smoothly for gradient and layering effects and dries quickly to reduce smudging. Dual tips — a wide chisel tip and a fine tip — allow both large-area rendering and precise line work. The included compartmentalised storage box doubles as a display stand and a carrying case for organised transport and storage.

Suitable for

• Illustration and concept sketches

How to use

Store markers horizontally before use and open the cap to select the required tip. Use the broad chisel tip for filling and blending larger areas and the fine tip for details and line work. Work on suitable paper such as sketch pads designed for alcohol markers to minimise bleed-through and achieve consistent colour. After use, close caps immediately to prevent ink evaporation.

Usage recommendations

Keep markers away from direct sunlight and do not leave uncapped. Not suitable for children under 3 years; use under adult supervision.
