I have found some creasing underneath collar and director of company in response he emailed me this
"Thanks for your email. I assure you that it's totally natural creasing. The leather we use is called "naked cow hide". This means that the leather hasn't been coated to hide the natural grain of the leather. It's only possible to do this with the highest quality leather. Other brands that use leather that is perfectly smooth coat the plastic to hide imperfections because they are using lower quality leather. The natural creasing you can see in the pictures is a mark of good quality, not bad quality"
Please advise is that right what he says I attach pictures of the creasing
