Highlighter Stabilo Boss 70 blue — Stabilo model 54K001C, chisel tip, water-based ink

Stabilo Boss 70 blue (model 54K001C) is a chisel-tip highlighter with water-based ink designed for marking and emphasizing text on paper. The marker delivers bright, consistent color for underlining, highlighting passages and creating color-coded notes. The chisel tip produces both broad strokes for full-line highlighting and fine edges for precise underlining, making it suitable for office, school and study environments.

Advantages

The water-based ink minimizes feathering on most paper types and dries quickly to reduce smudging. The chisel tip combines versatility and control, enabling both wide and narrow lines without changing tools. The robust plastic body provides comfortable handling and stable placement on desks, while the cap secures the tip and helps prevent ink drying during intermittent use.

Suitable for

• Highlighting and underlining printed and handwritten text
• Color-coding documents, notes and study materials
• Office filing, study preparation and classroom use
• Annotating books, reports and worksheets

Key specifications

• Tip type: chisel tip for dual-width marking
• Ink type: water-based ink formulated for paper
• Color: blue
• Line widths: broad stroke and fine edge from single tip
• Body: lightweight plastic barrel with protective cap

How to use

Remove the cap and hold the highlighter at an angle that matches the desired stroke width — lay the broad side flat for full-line highlighting or use the narrow edge for underlining. Apply steady, even pressure and move the marker along the text; allow a moment to dry before stacking pages or closing notebooks. Replace the cap securely after use to preserve ink freshness.

Usage recommendations

For best results, test the highlighter on a small area of the paper to check for bleed-through on thin sheets. Use the chisel edge for precise lines in margins and the flat side for fast highlighting of long passages. Store horizontally or with the cap on to maintain consistent ink flow.
