Outstanding Features of Magic Knock Retractable Marker
Smart Retractable Design, No More Lost Caps
The key advantage of Magic Knock is its convenient click mechanism. Users can easily operate the marker with one hand, making it ideal for workers on packaging lines, during inventory checks, or while taking quick notes.
High-Quality Permanent Ink with Excellent Adhesion
The product uses premium Japanese permanent ink, producing bold, clear, and quick-drying lines. It offers strong adhesion across various surfaces including cardboard boxes, plastic, metal, glass, tape, and wood. The smudge-resistant ink maintains legibility even in demanding working environments.
Versatile Line Width Options
The Magic Knock series offers two line size choices to meet diverse enterprise operational needs:
- Large Tip (Jumbo): Line width ranges from 2.5 mm to 3.0 mm, ideal for marking cartons, writing signboards, or creating large labels visible from a distance.
- Fine Tip: Line width ranges from 1.0 mm to 1.5 mm, perfect for writing detailed information on labels, product codes, or signing documents.
Cost Savings with Replaceable Ink Refills
To help businesses optimize operational costs and reduce environmental impact, Magic Knock features an easy refill mechanism. When the ink runs out, users can simply replace the refill core instead of purchasing a brand-new marker, significantly cutting down office supply expenses.
