Great value bulk pack
Buying 100 at once is very economical. The ink flows smoothly in most pens, though I had to wiggle one or two to get them started. Once flowing, they write beautifully and erase well with friction.

Kids love the magic erasing
My sons think it's magic that rubbing the ink makes it disappear. It has made doing homework much less frustrating for them. The only downside is that you have to press firmly to erase completely.

Smooth writing experience
I use these for my bullet journaling. The liquid crystal ink feels very smooth on the page, almost like a fountain pen but with the convenience of a gel refill. Erasing works perfectly with the back of the pen.

Universal fit confirmed
I was worried these wouldn't fit our specific brand of erasable pens, but the 3.4mm size is truly universal. They slid right into our existing holders. The black ink option is deep and dark.

Good but sensitive to heat
The pens work great, but be careful leaving them in a hot car. I noticed some writing faded slightly after being left on the dashboard on a sunny day. Otherwise, they are excellent for schoolwork.

Perfect for my third grader!
These refills are a lifesaver. My daughter makes a lot of mistakes when practicing her calligraphy, and being able to erase them cleanly without tearing the paper is amazing. The blue color is vibrant and true.
Q: Do these refills fit Pilot FriXion pens?
A: Yes, the 3.4mm universal size is designed to be compatible with most major brands of heat-erasable pens, including Pilot FriXion models.
Q: What happens if I leave the pen in the sun?
A: Since the ink is heat-sensitive, prolonged exposure to high temperatures (like a hot car dashboard) may cause the written text to fade or disappear. Store in a cool, dry place.
Q: Is the ink waterproof before erasing?
A: No, like most gel-based erasable inks, it is not waterproof. Please allow the ink to dry fully before handling to prevent smudging, and avoid contact with water.
Q: Can the ink be erased if the paper is old?
A: The erasure mechanism relies on heat generated by friction, not the age of the paper. As long as the ink hasn't been exposed to extreme heat previously, it should erase cleanly regardless of when it was written.
Q: Are all 100 pieces the same color?
A: This specific listing offers options for Pure Blue, Black, or a Mixed pack. Please select your preferred color variation from the dropdown menu before purchasing to ensure you get the desired ink color.
