Thais often wear more than one amulet on their necklace - this one allows for three to be held on one necklace. We have seen amulet necklaces with 7 amulets - usually worn by taxi drivers, or others that are in the Thai mafia - for protection from harm and evil spirits. We sometimes have some necklaces with 7 or 5. Just ask! This is an adjustable length necklace that fits everyone.
