We make our beaded jewelry with high grade stainless steel-nylon wire made in the U.S.A. The hematite beads are magnetic, and so are the clasps.
There's a free link to the British Medical Journal, suggesting the efficacy of a strong magnetic bracelet for the discomfort of the hip and knees. FREE SHIPPING for online orders. Magnetic necklaces and bracelets are custom made. Allow 2-4 weeks for delivery.
