This is a non-sale aluminum card case with the "SONY" logo. It's from about 30 years ago. It can be used on both sides. One side is a Memory Stick storage case, and the other is a card holder for business card size cards. If you remove the Memory Stick dividers, you can use both sides as business card size storage cases. I am also listing other card cases and rare items with different SONY group logos that were only available to employees, so please take a look.
