Marker Staedtler Lumocolor Duo double-ended green – model 200‑01421, dual tip (fine + broad), dry-safe, refillable

Staedtler Lumocolor Duo double-ended green marker model 200‑01421 combines two writing widths in a single refillable pen. One end has a fine tip for precise lines and detailed writing, the other end has a broad tip for filling, highlighting and bold strokes. The marker uses dry-safe ink formulated for non-porous surfaces, so it resists drying out when left uncapped for limited periods and provides clear, consistent green color on whiteboards, glass, laminated cards and many other smooth surfaces.

Advantages

The dual-tip design reduces the need to switch tools by offering fine and broad tips in one instrument. Refillable construction lowers waste and extends the usable life of the marker. Dry-safe ink maintains writing performance even if the cap is removed briefly, while the pigment formulation ensures good visibility on non-porous surfaces. The cap and barrel design provide secure closure and easy handling for both right- and left-handed users.

Suitable for

• Whiteboard notes and meeting room presentations
• Schoolwork, diagrams and exercise correction
• Glass, plastic and laminated surface labelling
• Crafting projects that require variable line widths
• Temporary signage and display marking

How to use

Choose the appropriate tip for the required line width and flip the marker to use either the fine or broad end. For writing on whiteboards or other non-porous surfaces, apply even pressure and move the tip smoothly to produce consistent strokes. Allow ink to dry for a short time before wiping or erasing. To refill, follow the manufacturer's refill instructions: remove the cap, access the refill point and insert compatible ink according to packaging guidance. Replace caps after use to maintain dry-safe performance.

Usage recommendations

Store the marker horizontally when not in use to promote even ink distribution. Test the green ink on an inconspicuous area of the target surface before extended application to confirm compatibility and ease of erasure. Keep away from porous materials and fabrics to avoid permanent staining; use on recommended non-porous surfaces for best results.
