Assorted Triangle Chalk

Hancocks assorted colours triangular tailors chalk. 12 pieces per box. Traditional tailors chalk made from china clay. These chalks are made so that mark(s) will stay on while work is in progress but are easily brushed off when work is finished. \n \n Customers are advised to test the fabric before starting work as some times the chemical finish in the cloth reacts with the chalk making it difficult to remove. If in doubt make the marks on the reverse of the fabric. The box contains an assortment of white, yellow, red, blue and black (mostly white and yellow).
