Using your Unicorns Happy Pack is super easy. For sketching or jotting, just grab one of the 12 #2 graphite pencils. When the tip gets dull, use the Mighty Sharpener to keep it sharp. The sharpener will contain the pencil shavings, but note that its color may vary. If you make a mistake, use the Rainbow Buddy Scented Eraser to wipe it away. Its large size makes it great for big mistakes. As for maintenance, keep the sharpener clean by emptying the pencil shavings regularly. Also, store the eraser in a cool, dry place to keep its scent fresh. Remember, all styles may not be exactly as pictured, and a comparable substitution may be made.
