Thanks, I think that could just be the lighting in the picture, but i´m gonna have a closer look, when the shirt gets shipped to me.

I´ve had a Korn Jersey Shirt from 2001 with the same Tag, so it seems to be legit, but still a odd tag.

Hi I´ve come across this Tag on a Marduk Shirt. You guys know when this tag was used, or in what region and if shirts with this tag are bootlegs?
Couldn´t find much on the internet except that is on some metal euro shirts.
