The magnetic necklace "Pip Magneloop MAX" has six 200 milliTesla magnets built into a 55 milliTesla magnetic powder-containing magnetic loop. Two types of magnetic force penetrate widely and deeply, relieving stiff neck and shoulders. Economical and can be used over and over again. This is a care product to relieve stiff shoulders that people who get stiff shoulders often will be happy about. By creating very fine grooves on the loop surface, the contact area with the skin is reduced by approximately 50%. We aimed to make it stress-free and comfortable to wear.
