The silver comb sent by the gold shop is not necessarily pure silver. The silver comb may contain other metals, alloys or other materials instead of pure silver, such as white iron ore. Therefore, it is impossible to determine whether the silver comb sent by the gold shop is pure silver. Pure silver has the functions of sterilization, anti-inflammation, anti-allergy, antisepsis and preservation, and has the functions of cleaning and repairing head grease and acne bacteria. However, if the silver comb is not pure silver, these benefits may not be obtained. Therefore, when buying or receiving a silver comb, it is best to confirm with the gold shop to ensure its material and quality.
