Cardas Golden Reference - why different colors?

Yes, same design, just cosmetic changes.

Thanks.

Same wire and design underneath the different cosmetics, though? I suspect so.

It seems that Cardas has changed their markings over the years due to counterfeiting problems. Here are some examples. If you search through the Cardas website, you'll also find info on changes in packaging, and some examples of counterfeits.

Cheers,
