Ok first off sorry I have so many questions!
This one is more of a understanding of what I could be looking at
I thought it was just gunk build up(and it very well could be!)
But it appears the PM is above and below the gunk
When I rubbed the stamp some of the darker PM
I don't wanna guess so I need some education
What am I looking at? (Attempt at re-using the stamp, gunk, glue)
I'll post a couple pictures to show as best as I can
