QULIS Quartz Power Necklace Retail Price: 19,800 yen This is a quartz power necklace in gold color. I've worn it two or three times, but the loop is too thin for me, so I'm selling it. This necklace uses the power of quartz to improve balance and core stability, providing power from both the outside and inside of the body. It's perfect for those who play sports or for everyday use. I definitely feel an improvement in my core stability when I wear it. It's not a magnetic necklace, so those who are sensitive to magnets can wear it without worry. The thickness of the cord is about the same size as the Colantotte mini. Please understand that I do not accept returns or cancellations after purchase unless there is a defect. #QuartzPower #QuartzNecklace #QuartzPowerNecklace #QULIS #QULISNecklace #Colantotte #Phiten #SportsNecklace #HealthNecklace #TitaniumNecklace #RubberNecklace
