Wax tailor’s chalk

The durable product by Argo 

This wax tailor’s chalk made from first class and non-toxic wax is characterised by its high adhesion, which makes it particularly suitable for woollen and upholstery fabrics.

The intensive line is easy to see on practically all fabrics. The markings stick well even on coarse weaves. Wax tailor’s chalk is especially useful for marking button holes. Because the markings are often hard or impossible to remove, they should be applied to the back of the fabric.
