Liquid dye suitable for all types of smooth and synthetic leather. Apply to clean, dusted, dry leather. Leave to dry for a few minutes. A quick brush with the Master Brush for leather or suede will restore the original colour. For a good result, keep the area to be treated well stretched during the operation. Use outdoors or in a well-ventilated place. For shoes, we recommend using the Master Shoe Tree or Boot Tree. First test the product on a small hidden area of the leather.
