^ Correct. Some are possibly Paulson, most are plastic. 6g 39mm chips are definitely plastic.Uh, these aren't ceramics, and they aren't new either. Chips like this have popped up from time to time for years. I'm still looking for some previous references but I'm 100% certain I've seen this kind of chip before, long before "Tina" chips became popular.
And blanks are most definitely not Paulson. The number of raw blanks known to have ever escaped the factory can be counted on one hand.
