Crayons of rich colors, made from wax with added oil, which allows for smooth drawing and good coverage of surfaces. The crayon is thicker than a regular wooden pencil, each wrapped in paper label, making it comfortable for small hands... not used to pencils. The child does not need to press hard for a line to appear. They draw on paper, cardboard, wood, stones, and other surfaces. They work wonderfully in various techniques in combination with watercolor, gouache, etc. Safe for children.
