I bought this necklace in October for my hangover. The necklace has a really good quality. The size and the safety lock can be set individually. Unfortunately, my cat has not brought back his collar after the last fight with a neighboring cat / a neighbor's cat home. It reveals itself easily that the safety lock really good rises, which was very important to me. Well, if this really great piece should now remain lost in the garden, I'll probably buy my cat one more time;)
