Tailor's chalk is an indispensable tool for marking and drawing on fabrics. With these Prym chalk pencils, very precise markings can be made on the fabric. A plastic brush at the end of the cap helps to remove the chalk lines. All markings should be removed before ironing. The chalk markers are available in a combination of white and blue or white and pink. Tip: It is best to try beforehand to see if the marking disappears.
