Heavy quality metal and I love the look. Have worn it now since I bought it and whether its psychosomatic, I think it helps me. I wear it 24/7, even in the shower and it still looks perfect. It shines and gets great compliments. It's brushed metal and subdued enough for my style.A HUGH THANK YOU - I bought one wanted to purchase some extra links, let me just say, I was overwhelmingly happy with the customer service. All vendors should take a note out of AK's customer service manual. Top notch, quick and courteous people there. A true class act.I purchased a second one as a gift - received with absolute adoration. Excellent overall!I never take it off. so not sure how durable the clasp is. and it still looks brand new 2 months later. jacuzzi, shower, massages, salt scrubs, sunscreens, nothing fazes this necklace. magnets are decent strength. i'd buy it again if i lost it. it matches my bracelet almost exactly from a different manufacturer (Willis Judd New Mens Golf Titanium Magnetic Therapy Bracelet) which is bonus.It's macho but heavy.Liked how it is smooth and flat. Very nice mans necklace.Nice exactly as advertisedProduct doesn't lay flat. Kinkier than the affair between D Trump and Stormy D. Gotta return this piece of crap. Worst online purchase I've ever made. Hopefully the seller will not give me any guff on my desire to return for full refund.Well so far so good my husband love this kind of Titanium Magnetic..necklace or either bracelet because he believes they work...so he's happy with it...Excellent product. Removed a few links and it fits perfect.
