Perfect for daily classroom use

I teach high school math and go through markers quickly. These Pentel KNOCKLE markers last significantly longer than other brands. The soft tip glides smoothly without squeaking, and the ink erases cleanly every time.

Best marker I've owned

I've tried almost every brand on the market, and this is by far the best. The retractable feature prevents the tip from drying out if you forget to cap it immediately. Excellent product quality.

Reliable and clean

Very satisfied with the purchase. The marker writes dark and bold, making it easy to read from the back of the room. Erasing requires minimal effort. A solid choice for teachers.

Soft tip is a game changer

The soft tip feels great to write with. It provides just enough friction for control but is smooth enough for fast note-taking. The large capacity means I haven't had to replace it in three weeks of heavy use.

Great ink flow, sturdy cap

The knock mechanism is very convenient so I don't lose caps during meetings. The ink flow is consistent. I deducted one star only because I wish they came in a bulk pack with more color options.

No more ghosting!

We switched our entire office to these markers last month. Previously, our whiteboards had stubborn ghosting stains. With the Pentel KNOCKLE, the boards look brand new after wiping. Highly recommended for professional settings.

5 FAQ

Q: Is the ink refillable once it runs out?

A: No, the Pentel KNOCKLE Whiteboard Marker is designed as a disposable unit with a large capacity tank. Once the ink is depleted, the entire marker should be recycled according to local guidelines.

Q: How long does the ink typically last with daily use?

A: With average daily use in a classroom or office setting, one marker can last approximately 3 to 4 weeks. Heavy continuous writing may reduce this duration slightly.

Q: Does this marker work well on glass surfaces?

A: Yes, this marker works excellently on non-porous surfaces including whiteboards, glass, and ceramic. The ink erases cleanly from glass when wiped with a dry or slightly damp cloth.

Q: Is the soft tip durable enough for rough whiteboard surfaces?

A: The soft tip is engineered to be resilient and maintains its shape well. However, for optimal longevity, we recommend using it on standard smooth whiteboard surfaces rather than textured or damaged boards.

Q: Are there different colors available for this specific model?

A: Yes, the KNOCKLE series is available in Black, Blue, Red, and Green. Please check our store listings to select your preferred color variant.
