The problem is, Scanavo uses since 1-2 years thinner metal for there steelbooks.
Wreck wrote this about the thinner metal problem:
"They use thinner gauge metal now almost primarily. Kind of like most things, try to figure out a way to make it cheaper. I'm sure if no competitors were around they could have kept the heavier gauge metal ... I've not inquired whether or not it was even still possible to order a steelbook in the heavier/thicker gauge like we used to see in all the old steels. (tho probably is if studio requests) However the last I saw was the TDK/BB France. Its very noticeable when comparing Embossed/Debossed steels of Old vs. New.".
