Works well but cap leaks slightly
The ink itself is great quality and writes very smoothly. My only issue is that the bottle cap seemed a bit loose upon arrival, causing a small leak in the package. The product inside was fine though.

Great for glass boards
We use glass whiteboards in our studio, and some inks stain them over time. This water-based formula cleans off pristine every time. The included absorber helps control the flow nicely.

Good value but messy filling
The ink quality is excellent and lasts a long time. However, filling the markers can be a bit messy if you aren't careful. I recommend using gloves. Once filled, the performance is top-notch.

Perfect for our classroom
These refills are a lifesaver for our school. The ink flows smoothly, and the best part is that it wipes off completely without leaving any ghosting marks. The odorless formula is great for sensitive students.

Excellent erase capability
As an office manager, I need whiteboards to look clean every day. This ink erases effortlessly even after being on the board for a few days. Highly recommended for high-traffic meeting rooms.

No more dry markers!
I bought this to save money on buying new markers constantly. It works perfectly with my existing large tip pens. The red and blue colors are vibrant, and the black is deep and bold.
Q: Is this ink compatible with Expo brand large tip markers?
A: Yes, this refill is designed to fit most standard large tip whiteboard markers, including major brands like Expo, provided the marker body accepts liquid refills.
Q: Can I mix the colors to create custom shades?
A: While technically possible, we do not recommend mixing colors as it may alter the chemical balance affecting the easy-erase property and could lead to clogging.
Q: How long does the ink last once the marker is refilled?
A: Depending on usage frequency, a single refill of a large tip marker typically lasts between 2 to 4 weeks of daily use in an office or classroom setting.
Q: What should I do if the ink dries out in the bottle?
A: If the ink appears thickened, you can add a few drops of distilled water and shake gently. However, our formula is designed to resist drying if the cap is sealed tightly after each use.
Q: Is the ink safe for children to use in elementary schools?
A: Absolutely. Our ink is non-toxic, odorless, and meets safety standards for use in educational environments involving children.
