Greetings from Vienna

Hey guys!

I'm now a proud owner of an IH-777S-21 and it's simply the best jeans I've ever had in my life. Cut, shape and fabric is amazing and fits perfectly to me.

Unfortunately I have an issue: from the first day of wearing I got some lined stains at the edge of the cuff:

As recommended I soaked them before first wearing for 15 min in my bathtub. I'm not a great expert since it's only my third selvedge jeans yet. But never experienced this with my other jeans before.

Is this normal for this fabric? Does it disappear with wearing and washing? Or what can I do to prevent this?

Thanks for your help!
