Yeah it's a mess.
First the 20 slim discs which is TY and states made in Japan is correct.
The 20 slim discs which is CMC and states made in Japan is most likely wrong.
The 50 spindle with AZO discs that states made in China is most likely wrong. (MAY be correct though.)
The 50 spindle with CMC discs that states made in China is probably wrong.
Btw went to another ELKJÃ˜P store, guess what? CMC in the 50 spindles there
I'll post a K-probe scan of those later.
The spindles is IDENTICAL, same 3 plastic rings on the top.
Only difference is to look at the top disc in the spindle (no need to open it) and see if it has a black serial number (half of the serial number is covered by the 3 plastic rings, but still half is visible). Those with black serial numer is AZO discs
