Specially formulated leads give a clear, fine line on fabrics. Lines are easily removed from most fabrics with the special Sewline Eraser or removed by dabbing with a damp cloth or washing. Simply rub off with the eraser or dab off with a damp cloth. Innovative ceramic technology creates a new generation of leads that are strong, non-gritty and more easily removed with the eraser or sponged off with a damp cloth. Comes with green lead.
