No more ghosting!
Finally found a marker that erases completely without leaving ghost marks on our glass whiteboard. The large capacity is a huge plus for our training center where we write all day.

Smooth writing experience
The liquid ink formula makes writing feel effortless. No need to press hard, which saves my hand during long brainstorming sessions. The cap seals tightly so the pen doesn't dry out.

Perfect for daily classroom use
I use these markers every day for my high school math classes. The ink flows smoothly without skipping, and the large capacity means I don't have to replace them constantly. Highly recommended for teachers.

Good quality, fast delivery
The marker works exactly as described. Ink is rich and black. I took off one star only because the cap can be a little tight to remove initially, but that also ensures it stays sealed well.

Great value for money
Solid marker for the price. The black is very dark and visible from the back of the conference room. It erases cleanly most of the time, though occasionally leaves a faint shadow if left on too long.

Best markers for our office
We switched our entire office supply order to SDI Shipai markers. They last significantly longer than our previous brand, and the consistent line width looks very professional on our project boards.
Q: Can I refill this marker once it runs out?
A: No, this marker is designed as a single-use disposable unit. Once the ink is depleted, the entire pen should be recycled according to your local plastic recycling guidelines.
Q: Is the ink toxic or safe for children?
A: The ink is non-toxic and conforms to standard safety regulations, making it safe for use in educational environments with students of all ages.
Q: Is this marker suitable for use on glass whiteboards?
A: Yes, this marker works excellently on both traditional melamine and modern glass whiteboard surfaces, providing easy erasure without residue.
Q: How long does the ink typically last with daily use?
A: With average daily usage in an office or classroom setting, one large capacity marker can last approximately 3 to 4 weeks before needing replacement.
Q: Does this come in other colors besides black?
A: This specific listing is for the Black color only. However, we do offer Blue, Red, and Green variants in separate product listings under the same SDI Shipai series.
