Sewline, Air Erasable Fabric Pen
The Sewline ink is a special formula that does not bleed and keeps a sharp edged, fine line. The drafting lines will then just vanish into the air over a few hours/days and will not reappear. Lines can also be erased by simply dabbing off with water. This pen has a fine, ceramic rollerball point.
Best suited for “instant” projects where the markings need only last the day.
