Has this box been resealed? I’ve not seen this sort seal on an old Japanese 60 pack booster boxes. The plastic join is across the front of the box rather than the base (as with all my boxes), it also looks raised and rough rather than flat and smooth. I suspect this box wont have the circle/oval windows on the sides.
My guess is YES
Looks like soft plastic as well, similar to that found on newer boxes. I’m 99% sure these boxes were sealed with that old brittle plastic. Definitely a bit shady.
how about this?:

Yeah that has been sitting on ebay for ages even though the price isn’t too bad. If the seal was original both sides would have oval shaped empty spaces.
I don’t have any ADV boxes to compare directly, but my E series and PCG box both have oval spaces like nauticads mentioned.
