1. Retractable and Clip Design: The highlighter features a retractable mechanism—simply press the cap to retract the pen tip automatically. It includes a clip for easy attachment to books and portability. Note: Each pen comes with a stopper to prevent ink from drying out. Please seal the tip with the stopper immediately after use. 2. 6Color Highlighter Pen Set: This stylish set includes six vibrant colors—yellow, blue, pink, purple, green, and orange. The bright, rich pigments ensure your highlighted key points stand out clearly. 3. Soft Chisel Tip: Equipped with a soft wedgeshaped tip, the 4mm wide edge effortlessly marks entire words, while the 1mm fine edge is ideal for underlining. It glides smoothly without damaging paper. Tip: For results, tilt the pen at a 45degree angle. 4. LeakProof and QuickDrying: The waterbased ink dries quickly, preventing smudges on hands or sleeves. The ink flows evenly for smooth, streak writing, making it convenient and userfriendly.
