The Elite Necklace from Trion:Z combines fashion and function. Titanium accents compliment the highly polished, SUS316L Stainless Steel pendant giving this sporty necklace an upscale look. Our unique Alternating North-South Polarity Orientation is used, with eight 1,000 Gauss magnets, to create a larger magnetic field flow. Alternating polarity eliminates dead zones that are created when magnets are placed side by side with poles aligned. The magnet capsules are adjustable along the waterproof, silicone cord.
