To use this Kryolan Silicone Colorizer, first, make sure your silicone surface is clean. Squeeze a small amount of the color paste onto the silicone and use a brush or a spatula to spread it evenly. You can mix different colors to create your own unique shades. When you're done using it, close the tube tightly to prevent it from drying out. Store it in a cool, dry place away from direct sunlight. Avoid getting it in your eyes or mouth. If it accidentally gets on your skin, wash it off with soap and water.
