The 0.9 mm diameter of BOHIN chalk pencils enable a neat and precise job of tracing quilting patterns or transferring other patterns. For better visibility we recommend to adjust the colour of the lead according to the colour of the fabric to be marked. The leads are supplied in a sturdy plastic box and thus can be protected and carefully put away. Available in a variety of colors. Each sold separately. This package contains six (6) pieces of 0.9 mm chalk pencil leads. Imported.
