Long story short, we bought this booster case from mercari through a proxy. The seller had over 300 5 star ratings, the booster case had some brown tape over it (the listed picture does not) although it was still sealed and the booster boxes inside had the right shrink wrap (softness and style of wrapping is the same). Once we opened it, it was apparent that it was a tempered box with junk cards.
Lesson learned: if you received a case with tape over it, it is highly likely that it has been tempered. Do not buy using proxies as they do not cover whats inside the box, buy em from a trusted local seller if its a high value item.
