Using this eyeliner pencil is easy. Just gently glide it along your waterline to create a defined eye look. For best results, start from the inner corner of your eye and move towards the outer corner. When you're done, there's no need to worry about smudging as it's resistant to sweat and sebum. However, avoid rubbing your eyes right after application to prevent any accidental smearing. To keep your eyeliner pencil in good condition, store it in a cool and dry place. And if it becomes dull, you can sharpen it with a regular eyeliner sharpener.
