The Sewline Air Erasable Roller Ball Pen contains an advanced technology ink system with 0.8mm ceramic roller ball for fine lines. The Sewline ink will disappear within 2-10 days from most fabrics or can be immediately erased with water. 

Remember to remove any ink marks from the fabric before ironing. Most fabrics contain sizing, which strengthens and conditions fibers, and ironing the ink may inhibit the ink's removal.

Always test your fabric before beginning a project.
