Using this necklace is a breeze. Simply open the pear - shaped lobster lock and put it on around your neck. To adjust the length, just find the right spot and close the lock. When wearing, avoid contact with harsh chemicals like bleach or strong detergents as they can damage the gold. Also, take it off before doing strenuous activities to prevent it from getting tangled or broken. For maintenance, gently clean it with a soft cloth after each use to keep it shiny. You can also take it to a professional jeweler for a deeper clean every few months.
