Have one and one ordered for me for my brother. The leather collar is very stable, but also initially smelling strongly of leather. I think that's normal, my girlfriend has become almost insane, laughing. After a few days with showers and so the smell was but disappeared.
The stainless steel pendant is also top. No rust or tarnish. (PRO TIP: And if you have eaten onions times can you rub it the smell of the fingers). )
Well all in all 5 of 5 ..'ll be back!
