AIHAO 6261 Jumbo Chisel Highlighters 6-Pack

Ergonomic Jumbo Barrel & 1–4mm Versatile Chisel Tip

The AIHAO 6261 Jumbo Check Line Highlighter 6-Pack brings comfortable ergonomics and brilliant fluorescence to daily study, office document review, and textbook notation. Engineered with an extra-wide, pocket-sized flat barrel, each highlighter rests naturally in hand to reduce finger fatigue during extended reading sessions. The durable fiber chisel nib allows seamless transitions between a 1.0 mm fine line for detailed underlining and a 4.0 mm wide stroke for full-line highlighting. Filled with AP-certified non-toxic, water-based quick-drying fluorescent ink, these highlighters emphasize text vibrantly without smudging ballpoint notes or bleeding through notebook paper. The 6-color set includes Fluorescent Red, Orange, Yellow, Green, Blue, and Violet.
