Best bulk buy for the office
Ordered a box for our mailroom and everyone loves them. The ink flow is consistent from the first mark to the last. No skipping or blotching. Will definitely reorder when we run low.

Great durability, strong smell initially
The ink is incredibly durable and survives rain and handling without fading. My only minor complaint is the initial chemical smell when you first uncap it, but it dissipates quickly. Excellent value for the price.

Perfect for our warehouse shipping labels
We go through hundreds of markers a month in our distribution center. These oil-based markers write clearly on corrugated cardboard even in dusty conditions. The quick-drying feature prevents smudging when we stack boxes immediately after labeling.

Essential for small business shipping
As an online seller, clear addressing is crucial. These markers provide bold, legible lines that courier scanners can read easily. The broad tip covers large areas quickly, saving me time during peak shipping hours.

Solid workhorse marker
Used these for marking materials on a job site. They held up well against sun exposure and light rain. The tip stayed firm even after heavy use, though I wish the cap clicked a bit tighter to prevent drying out if left open.

Writes on everything
I tested this on plastic bins, metal shelving, and glass windows in our office. It adheres perfectly to all surfaces and doesn't wipe off with a dry cloth. You need alcohol to remove it, which proves its permanence.
Q: How long does the tip last before wearing down?
A: Under normal usage conditions on cardboard or paper, the durable fiber tip typically lasts for several thousand feet of writing line. Rough surfaces like concrete may reduce lifespan slightly.
Q: Does this work on glossy plastic packaging?
A: Yes, the oil-based formula is specifically engineered to adhere to non-porous surfaces like glossy plastic, metal, and glass without smearing.
Q: Can I refill these markers?
A: No, these markers are designed as single-use disposable units to ensure consistent ink quality and pressure. Refilling is not supported and may damage the pen structure.
Q: Is the ink toxic if it touches skin?
A: The ink is non-toxic but is designed for industrial and office use, not for skin application. If contact occurs, simply wash with soap and water. Avoid contact with eyes.
Q: Can this marker write on wet surfaces?
A: While the ink is waterproof once dried, we recommend applying it to dry surfaces for the best adhesion and immediate clarity. Writing on wet surfaces may cause the ink to bead up before setting.
