Best for outdoor projects
Used this to label garden stones and PVC pipes. Months later, the writing is still crisp and hasn't faded despite being in direct sunlight. Highly recommend for outdoor use.

High capacity lasts forever
I've been using the same pen for three weeks of heavy construction site marking and it's still going strong. The ink flow is consistent and never skips.

Good value for money
Solid marker for the price. The thick tip covers well on dark surfaces. Just make sure to cap it tightly after every use to prevent the tip from drying out.

Great marker, strong smell initially
Does exactly what it says on the tin. Very durable mark that survives rain and sun. Only giving 4 stars because there is a slight chemical smell when you first open it, but it dissipates quickly.

Bold and permanent
The tip is huge which makes it great for writing on large boxes from a distance. The black is very deep and opaque. It writes smoothly on rough surfaces like concrete blocks.

Perfect for industrial labeling
I use these markers daily in our warehouse for labeling metal crates. The ink dries instantly and doesn't smear even when handled immediately. Truly waterproof as advertised.
Q: Does it work on glossy plastic?
A: Yes, the oil-based formula adheres exceptionally well to non-porous and glossy surfaces like plastic, glass, and polished metal.
Q: Can I refill this marker when it runs out?
A: No, this specific model is not designed to be refilled. It is a disposable high-capacity unit intended for single-life use.
Q: What is the shelf life if unopened?
A: If stored in a cool, dry place with the cap sealed, an unopened marker has a shelf life of approximately 24 months.
Q: Will this marker write on wet surfaces?
A: While the ink is waterproof once dry, we recommend wiping the surface dry before application for the best adhesion and line quality.
Q: Is the ink toxic if it gets on skin?
A: The ink is non-toxic but is designed for industrial surfaces. If it gets on skin, please wash thoroughly with soap and water or use an oil-based remover.
