Shuttle Art Dual Tip Alcohol Based Permanent Markers are rated for 300 meters of continuous use which provides you a vast amount of ink per marker. TRIANGULAR SHAPED: Unique ergonomic triangular shaped barrels for an easy and comfortable no slip grip. Unique shape also prevents markers from rolling off smooth surfaces. Bonus Storage Case included! Our black zippered case is perfect for storage as well as traveling. DUAL TIP: These markers have both a 7mm broad tip for quick coverage and a 1mm pointed bullet tip for highlights, shadows, bullet points, sketching and general writing. In order to prevent the ink from bleeding in use, the tip should not stay on the paper for a long time. EASY TO BLEND INK: Shuttle Art Dual Tip Markers blend and layer well without leaving streaks behind and dry quickly. Blending colors is a breeze by layering one unique color onto another creating an unlimited color palette. Markers need to write on a specific mark paper so that it doesn't bleed to the next layer. To prevent the marker from drying and ink leaking, please recap and keep the marker laid flat after use.
