The Chaco Liner Pen by Clover has a fine point that permits accurate drawing of both straight lines and free hand curves. The refill cartridge for the Chaco Liner Pen (sold here) is easy to replace when the powdered ink runs out. 

Choose chalk color: white or blue

Features:

• Fit the cap to bottom of the pen during use for added length and easy drawing.

Notes for Use

• Test on a piece of scrap fabric to be sure that the lines and marks can be erased (do not use fabrics that are not washable)

• Ironing or dry cleaning may make the marks permanent
• Fasten the cap firmly to the body when not in use, to prevent spills
