SFAIH Black Permanent Markers — Fine Point 100-Pack, 1s Quick-Dry & Waterproof

SFAIH Black Permanent Markers Bulk is a 100-piece set of fine-point, fast-drying black markers built for long runs of clear, waterproof labeling on multiple surfaces.

Whether you manage a warehouse, run a classroom, or pack shipments from home, these markers are engineered to stay sharp, dry fast, and resist smudging. Each pen in this bulk pack uses high‑purity carbon ink and a wear-resistant fine tip to deliver consistent black lines and up to thousands of inches of continuous writing. The airtight caps and stable ink formulation help maintain performance even after storage.

How quickly do these markers dry and why does that matter?

The SFAIH fine-point pens dry in about one second under normal conditions, reducing the risk of scuffs and ink transfer to hands or adjacent pages. Faster drying keeps work neat and speeds up high-volume tasks like packing, filing, and labeling.

• 1-second quick-dry formulation for immediate handling
• Less smudging on paper, cardboard, and coated surfaces
• Ideal for fast-paced workstations and assembly lines

What surfaces will these permanent markers write on reliably?

These markers are formulated to mark a wide variety of materials, including plastic, metal, wood, ceramic, fabric, and cardboard. The high-adhesion ink resists water and wiping, so markings stay legible in storage, transport, and low-temperature conditions.

• Works on plastic bins, tape, and coated cardboard
• Suitable for metal shelves, ceramics, and glass labeling
• Performs on fabric tags and cold-chain environments

How long does each marker last and how consistent is the ink?

Each marker is designed for extended use, supporting extensive continuous writing thanks to a high-capacity ink reservoir and a durable tip. The carbon‑based ink produces dense, uniform black strokes from the first mark to the last.

• High-capacity ink for long-run projects
• Wear-resistant fine point maintains line quality
• Estimated thousands of inches of uninterrupted writing per pen

How should I store and care for these markers to keep them usable?

To preserve performance, replace caps immediately after use and store pens horizontally when possible. The caps are designed to seal tightly, which helps prevent drying during longer storage periods.

• Close caps fully after each use to maintain airtight seal
• Store horizontally to ensure even ink distribution
• Keep away from extreme heat to prolong ink life
