The American version of ck and the mainland version of ck are not exactly the same, and the differences are as follows:

1. Different countries: American brands, China has agents, but American migrant workers can't buy them casually.

2. Different trademarks: the American version of the trademark is gray, representing the United States.

3. Different sales channels: sales outside the United States, including Chinese mainland, Hongkong, Italy, Bangkok, etc.

4. The style of working fabric is much better than that of ordinary ck in America.

The above is the difference between the American version of ck and the mainland version of ck, I hope it will help you.
