When I first started collecting I purchased a MIB G1 Prowl with prowl still sealed to the bubble - only when I got it the home I found someone had just put a classics gold boxed prowl inside the original G1 box. Not that i'm still bitter about it or anything
There are plenty of these Chinese issues floating around in Australia - always check the manufactures stamp - if the country of original is covered over its a giveaway. The boxes are easy tells from the front (grey border is usually different) and the back - copyright blanked over as in your example.
