About This

• <b>1.0mm Bold ST Tip | Assorted Black + True Blue Quick-Dry Ink</b> The upgraded durable ST bold tip delivers consistent, high-contrast lines for dual use: deep black ink for official signing, key note highlighting and heavy writing; saturated true blue ink for teacher grading, cross-subject color coding and document annotation. Zero bleed-through even on thin paper, 2-second fast-dry formula leaves no smudges on pages or hands, friendly for left and right-handed users. Advanced ink supply ensures zero skips or breaks for uninterrupted writing.
• <b>Ergonomic Non-Slip Grip + Sleek Gradient Black-White Barrel</b> The contoured matte non-slip grip fits natural finger posture perfectly, reducing hand soreness even after 3+ hours of continuous writing or marking, and fits all hand sizes comfortably. The unique scratch-resistant gradient black-white barrel is fingerprint-proof, standing out from boring solid-color pens for a modern, premium look that works for both school and office scenarios.
• <b>Bold-Tip Optimized Large-Capacity Long-Lasting Ink</b> Our upgraded ink core is specially calibrated for 1.0mm bold tip output, holding 2x more ink than standard 1.0mm gel pens, supporting up to 500+ meters of continuous writing per pen. No need to replace pens frequently even during busy exam seasons or heavy grading work, eliminating the frustration of running out of ink mid-task, saving you time and repurchase cost.
• <b>One-Click Retractable Design with Anti-Accidental-Trigger Lock</b> The smooth one-click mechanism lets you extend/retract the nib with a single hand, no need to worry about losing pen caps. The built-in reliable lock prevents accidental nib pop-out in bags, eliminating ink stains on your clothes, backpack or lesson plans. The high-quality spring lasts over 10,000 presses without loosening, staying responsive for long-term daily use.
• <b>Dual-Use Value & Hassle-Free Customer Support</b> This mixed black and blue bold pen set eliminates the need to buy separate single-color packs, fitting all daily needs: teachers grading with blue ink and signing with black ink; students writing notes with black and marking key points with blue; office workers signing documents with black and annotating with blue. All products pass strict quality inspection before shipping, and our 24/7 customer support team is always available to address any concerns promptly.
