About this item

• Alcohol Based & Square Pen Holder: Keep Smiling alcohol-based ink has passed German SGS testing and European safety certification according to European standard EN71-3 and obtained MSDS certification. The ink is low in odor and toxic-free. Keep Smiling marker pens hold more ink, and the broad tip can write up to 100 meters long and the fine tip can write up to 530 meters long.
• Color-coded caps with a quadrilateral shape. The color-coded caps help you organize and easily identify colors. The quadrilateral shape makes them comfortable to hold and prevents the pens from rolling off smooth surfaces.
• Perfect Multipurpose Gift Idea: Keep Smiling Alcohol Based Markers are perfect for architectural design, advertising, landscape, highlighting, coloring books, drawing, illustration, sketching, beginner lettering, and other forms of graphic design. Keep you well organized and make the perfect gift for birthdays, back to school, Thanksgiving, and Christmas.
• Dual-Tip Marker: Keep Smiling dual-ended markers feature a 1mm pointed tip for detail and a 1-7mm slanted tip for quick coverage. Professional markers with intense, vibrant colors that blend well and don't smear, adding a touch of elegance to your artwork.
• Warnings: The marker is non-toxic and acid-free, safe for children, students, adults, and artists. To prevent ink bleeding during use, do not leave the tip on the paper for too long. Markers need to write on marker paper with certain properties so they do not bleed through to the next layer. To prevent the marker from drying out and bleeding, replace the marker cap and lay it flat after use.
