Pen style Chaco liners fine point permits accurate drawing of both straight lines and free hand curves. The fine point makes lines and marks more visible and is easy to use with a straight edge ruler. Powder can be brushed away and any persistent marks can be washed with detergent.
Available in 5 different colors - blue, pink, white, yellow and silver.
Refill cartridges are available here.
As with all markers, test on a piece of scrap fabric to be sure that the lines and marks can be erased. Ironing or dry cleaning may make the marks permanent.
