☆ Oil Pastel 24 Colors ☆ [Features] These oil pastels use safe pigments and offer vivid colors. Oil pastels are not easily broken, making them easy to use for everyone from children to adults, with a comfortable thickness and softness. They blend well, allowing for easy color mixing through layering. After drawing, you can smudge them with your finger to fix them to the paper, or apply heat treatment with a hairdryer for a more permanent finish. By applying a light color first and then layering a darker color on top, you can create a scratch effect by scratching the surface with a needle or similar tool. They can be dissolved with turpentine. [By tracing the surface of an oil pastel drawing with a brush soaked in turpentine, you can create a blurring effect.] When combined with watercolor paints, the oil pastel areas will repel water, creating a very interesting effect.
