Using this pack is a breeze. When you want to start drawing or writing, just grab one of the 12 comic - themed graphite pencils. Sketch your ideas freely and jot down notes as needed. If you make a mistake, take one of the 3 ninja erasers and gently rub it over the area. The eraser is super agile, so a few quick strokes will get rid of the mistake. When your pencil gets dull, use the Mighty Pencil Sharpener. Insert the pencil into the sharpener and turn it slowly until it's sharp again. As for maintenance, keep the pack in a dry place to prevent the pencils from getting wet and the erasers from drying out. Also, remember that the actual items may differ slightly from the pictures, but you'll still get a comparable and high - quality product.
