Coloring sticks, also known as crayons, are a popular art supply used by children and adults alike. They come in a variety of colors and sizes and are made from wax or oil-based pigments. Crayons are typically used to draw and color on paper, but can also be used on other surfaces such as wood, fabric, and even glass. Crayons are an essential part of any art kit and are a great way to express creativity.
