Pilot Frixion felt pens and inks have the particularity of fading under a heat source, and they have become the darlings of embroiderers all over the world! It is indeed the ideal ink to trace a design to be embroidered on a fabric: a blow of iron or foehn, and the line disappears, it remains only the embroidery.
The Pilot Frixion Fineliner has a fine, durable lead that marks fabric better than its ballpoint counterpart. A must-have!
