Solid refill for the price
Can't beat the price for a pack of ten. They last a decent amount of time even with daily use by an elementary student. Will definitely purchase again when we run out.

Good value, works as expected
Bought these for my son's fountain pen. They fit the 3.4mm converter perfectly. The ink flows smoothly, though it takes a firm rub to completely erase the text in colder weather.

Smooth writing experience
These refills write very smoothly on standard notebook paper. No skipping or blotching. The fact that they are replaceable saves money compared to buying whole new pens every time.

Perfect for my third grader!
My daughter loves these refills. She makes mistakes often when learning cursive, and being able to erase them cleanly without messy white-out is a game changer. The blue color is very vibrant.

Decent but fades in heat
The erasing feature works well, but I noticed that if the notebook is left in a hot car, the writing starts to fade. Good for schoolwork, but maybe not for permanent records.

Great black ink option
I specifically needed the black color for my 5th grader's math homework. The line is consistent and dark enough to be easily read, yet still erases cleanly with the pen tip.
Q: Is the ink safe for children?
A: Yes, the ink is non-toxic and formulated to be safe for elementary school students. However, it is not intended for ingestion.
Q: Can I use this for official documents?
A: We do not recommend using heat-erasable ink for legal, financial, or official documents, as the text can disappear if exposed to high temperatures.
Q: How exactly do you erase the ink?
A: The ink is heat-sensitive. You can erase it by rubbing the written area firmly with the friction tip located on the end of the compatible pen, or by using a standard eraser vigorously to generate heat.
Q: Does the blue ink look light or dark?
A: The Crystal Blue ink provides a vibrant, medium-dark blue line that is clearly visible on white paper, making it ideal for grading or color-coding notes.
Q: Do these refills fit all fountain pens?
A: These refills are designed specifically for fountain pens that accept a 3.4mm caliber converter. Please check your pen's specifications before purchasing.
