As far as I can see they are just run of the mill, buy anywhere & everywhere normal clunk, click snap on collars with fancy stuff someone stitched around them, maybe from waste rags.
I think its an excellent get rich quick business idea from someone somewhere - if you click the link below thats the exact same, but bare, type collar on my dog but without the extra frills.............I guess the real answer to your question is that if you feel good about having one then get it & enjoy it!
