Fine Line, Smooth roller ball point pen. Lines vanish into the air in 2-3 days.
If you want a fabric marker that gives clear lines that are not furry, do not bleed and can be easily erased this Sewline pen is for you.
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 days and will not reappear. Lines can also be erased by simply dabbing off with water. This pen has a fine, ceramic rollerball point – not one of those hard, scratchy nylon points.
