When a consumer requires the 5x5 PID key 
they should remove enough of the scratch off 
so they can read the key underneath.
Even if all silver material is removed the 
clear label will remain.
Any attempt to remove or peel off the 
underlying clear label will result in 
damage to the COA which may render 
the product key unreadable. This 
security feature is by-design.
