|Eye pencils are especially important to sharpen.|
Cosmetics in pencil or crayon forms are wonderful, especially for what they can do for beauty when you keep them sharp for the best application. Sharpening helps with drawing a better line, but it also serves another purpose–-getting rid of bacteria.
So give your pencils a quick twist or two in your sharpener before reusing them again. You won’t be wasting all that much in what is shaved off, but will be staying safe in the process.
