P610950 Prym Chalk wheel “Mouse”. Ideal for freehand marking and marking on all fabrics. The fine gear at the top of the mouse shaped chalk wheel leaves a clearly visible fine chalk line, which can be removed easily by brushing or washing after the sewing of the fabric. The level of chalk in the cartridge can be seen through a window. Replacement chalk cartridges are available for ordering with white or yellow chalk powder. A grippy cap reliably closes the chalk wheel. This practical chalk wheel was awarded the Red Dot Design Award in 2010. 610950 1pc
