Do me a favor when it comes in.
Can you measuer how thick it is?
There are several ways to do this without fancy measuring tools if you need to know how.
I would like the bottom and the side if at all possible.
It doesn't have to be to the thousands.
The bottom just take a ruler or straight edge and lay it across the top and hanging out one side.
Measure the edge to the bottom.
Measure the edge to the flat surface it is on.
The difference between the two readings is the thickness.
