Why are phiten necklaces better then RAKUWA? Is there a difference? Should i get a phiten or RAKUWA?

On ebay i saw a really cool necklace but i didn’t no if i should get it and plus it was all the way in Hong Kong

Phiten necklaces and RAKUWA Necklaces are the same – they are both made by the company Phiten, but in the US they are called “Titanium Necklaces” whereas in Japan, the product name is “RAKUWA Necklace”. (In Japanese, “Raku” means ease or comfort, “wa” is ring/circle.)
However, I would be careful about buying a RAKUWA Necklace on ebay – there has been a recent onslaught of counterfeit Phiten necklaces, especially with the Japanese “RAKUWA” versions. They look almost exactly the same, but counterfeit ones don’t have the Phild processing that gives Phiten products their energizing benefit. The quality of the necklace itself is often inferior as well.
What necklace is it, by the way?
