Beginning August 2014 I ordered this real leather necklace with a Celtic cross pendant at Amazon.com. And I use them for fixing this cross pendant I wear almost every day. I had indeed at the beginning to get used to it, to close the tunnel screw cap and also to re-open. But now I'm now as a man * wink * pretty well with it. Only when my fingers are wet, such as after washing hands or showering, it works not at all so that I can connect the twist lock. But with dry fingers then comes the closing and opening of the twist lock easily. Otherwise me this tunnel-like screw cap alone thus very well that he is not very noticeable, because it is in diameter nearly as thin as the real leather chain itself. So far, both this real leather chain and the tunnel-rotation lock are all stayed with me. Therefore I can only recommend itself so far this real leather chain - especially for men, who do not necessarily want to wear this thin chain around his neck. So a genuine leather necklace looks just from a bit masculine.
