Cleaner than chalk
I switched from tailor's chalk to these pens for detailed pattern work. The lines are much finer and more precise, and the heat activation is reliable every time.

Consistent flow
The ink flows smoothly without skipping. It takes about 10 seconds of direct heat to fully disappear, which gives me enough time to reposition if needed.

Essential for garment prototyping
As a fashion student, these are essential. They allow me to make temporary adjustments on muslin without worrying about permanent stains. Highly recommended.

Good but sensitive to humidity
The product works as described in dry conditions. However, I noticed the marks fade slower if the workshop is very humid. Still useful for general layout tasks.

Perfect for my shoe repair shop
These refills are a game changer. I use them to mark stitching lines on leather, and they vanish completely once I use my heat gun. No residue left behind.

Works well with an iron
Great for marking fabric before cutting. The ink disappears quickly under a warm iron. Just make sure not to press too hard or the line might indent the fabric slightly before fading.
Q: Do the marks come back if it gets cold again?
A: Unlike some friction inks that reappear in freezing temperatures, our formula is designed to remain faded after the heat threshold is met, ensuring your final product stays clean.
Q: How many refills are included in one order?
A: Each package contains exactly 10 refills. We also offer bulk packs of 50 for professional workshops on our store page.
Q: Can I use this on synthetic leather?
A: Yes, these refills are safe for use on both natural and synthetic leather. However, we always suggest testing on a small, inconspicuous area first to ensure the material can withstand the heat required to fade the ink.
Q: Will these refills work in a standard Pilot FriXion pen?
A: Yes, these refills are designed to be compatible with most standard gel pen bodies, including popular friction pen models, provided the diameter matches.
Q: What happens if I leave the marked fabric in a hot car?
A: Since the ink is heat-activated, exposure to high temperatures (above 60°C) may cause the marks to fade prematurely. We recommend storing marked items in a cool place until you are ready to set or remove the lines.
