Black Pilot Frixion ball pen, Fine point 0.7mm. Black bold marking ink that completely removes with heat and leaves no residue. Great for marking patterns and lines. As with all pens with Frixion's unique thermo-sensitive ink, you can erase cleanly using your iron or alternatively your hair drier if you do not wish to press your project.
Keep in mind faint lines may reappear when exposed to extreme cold, although can then be removed again.
Always test first on an inconspicuous area.
