Tailor's Chalk Set of 4 pcs in Box

Tailor chalk becomes your helper for drawing cuts. It is packed by 4 pieces in a plastic case.

We have tried: We tried the chalks, they are hard and they drew poorly on the knit, the drawn line is not very visible. They drew well on the canvas, but the trace of chalk was poorly cleaned from the materials, after washing on the material after the blue and yellow chalk, a visible line remained.
