What the heck is this??

I know how it got into my tire, but what it is escapes me. I thought it was one of those cable . . . grommet . . . things but on second glance that does not pan out.

Whatever it is, it's now a $20 part . . . which is how much the tire repair cost me.

Looks like a portion of a numbered bolt seal.

Thank you! I think you have it!! Wonder if I can track the sn to figure out where to get my $20 back?
