,I want to share my experience with potential buyers to differentiate genuine CK men's underwear from counterfeits.

There are many ways to identify CK counterfeits. However, it may be difficult at times because some of them look so real.

Today, I will talk about a very simple method. The font used by "Calvin Klein".
This includes the space between the word "Calvin" and the word "Klein".
Also compare the space between each characters.

Some counterfeits have too small space between the word "Calvin" and "Klein".

Refer to the 3 pics attached.

Ths fake ones ghas very different font. The space between "Calvin Klein" is also smaller than real ones.
