Marker Sharpie W10 flat tip black — permanent marker with flat chisel tip

Sharpie W10 flat tip black is a permanent marker with a flat (chisel) tip designed for clear, consistent lines on a variety of surfaces. The marker delivers quick-drying, fade-resistant ink suitable for labeling, writing and drawing on paper, cardboard, plastic and many coated materials. Its chisel tip creates both broad strokes and fine lines depending on the angle, offering controlled results for office, school and home tasks.

Advantages

The flat chisel tip provides versatile line widths from broad to fine with a single marker. Permanent, fast-drying ink reduces smudging and maintains legible markings over time. The marker’s body is lightweight and easy to grip for extended use, while the pigment formulation resists fading on most surfaces. Designed for dependable ink flow, this Sharpie model produces consistent coverage and clear contrast on light and dark backgrounds.

How to use

Hold the marker at an angle to change stroke width: use the broad edge for wide lines and rotate to the narrow edge for finer lines. Test on a scrap piece of the target material before marking visible areas to confirm ink adhesion and appearance. Replace the cap securely after use to prevent the tip from drying out. For best results on non-porous surfaces, allow ink to dry fully before stacking or handling.

Usage recommendations

Store horizontally or with the cap securely closed at room temperature. Avoid prolonged exposure to direct sunlight and extreme heat to preserve ink quality. For surfaces exposed to outdoor conditions, consider testing permanence and compatibility; on very smooth plastics or glossy coatings, adhesive labels may provide longer-lasting identification.
