Thanks for your efforts but correct me if I am wrong: the foto with the jeans, where is the unique code that nobody could copy?
There is a crypto tag on the leather logo. This is the very way to protect against counterfeit. If the product doesnt have a crypto tag, although the manufacturer uses it, it's likely that you have a counterfeit product.
Interesting, but can't that tag easily be damaged or torn apart from the product (even accidentally)?
The developers claim that these jeans were washed dozens of times, and in general are used daily. The crypto-tag works. Stunning wear resistance.
