Oil crayons adhere to almost all surfaces, even smooth ones. No fixing is required. They are water-resistant, free of heavy metals, can be wiped (similar to oil painting) and they are permanent, but soluble with solvents.
The colors provide good coverage, are deep and rich and have a very soft, intensive and smooth color stroke quality with lusterless to matte or satin finish.
Oil crayons are difficult to correct and are not erasable. They should not be subjected to higher temperatures (approx. 122 ' fahrenheit), as they become soft when heated due to their high wax content.
Oil Pastel Crayons are available in packages of 12, 24 and 36 colors.
