These tank-style highlighters focus on providing a significant ink reservoir, offering one of the highest ink-to-plastic ratios in the category. The SmearGuard ink is a specialized chemical formula designed to work with inkjet printouts more effectively than many water-based alternatives. The sintered polyethylene tip is built to maintain its chisel geometry for approximately 25,000 words.
The polypropylene body is designed for high chemical resistance but should be handled with care to avoid heavy impacts. Because of the large internal air volume, it is vital to apply more than 5N of force to ensure the cap "clicks" into a full seal, preventing premature evaporation. This model is best suited for standard-weight office paper due to its generous ink flow.
The 4-count pack provides a steady supply of fluorescent yellow, the industry standard for high-visibility marking. The large barrel design is intended for desk use where longevity is prioritized over a slim profile.
For a set that includes a wider variety of colors for creative projects, the Sharpie S-Note Creative Markers offer 24 different shades.
