Hello all,
I got a new jewelers loop and with it I can see a horizontal line (WHEN VERTICAL) on the bottom edge of the security strip on either the front or back. Does anyone know if this may be a natural seam? I'm seeing it on various prefixes. Can't take photos under magnification.
Thank you.

I see it on one of mine but not the other. I have no idea what it is. Here's a pic:
