Using this makeup brush is easy. First, dip the brush into your preferred eyelash product. Then, gently apply it to your eyelashes in an upward motion for a natural look. When you're done using it, wash the brush with mild soap and lukewarm water. Gently squeeze out the excess water and let it dry flat. Make sure to keep it away from direct sunlight when drying. Also, avoid dropping the brush, as the metal handle might get dented. With proper care, this brush will serve you well for a long time.
