Hey everyone,
I was weighing the packs from a booster box of Korean ADV (Ruby & Sapphire) I have and they were all approximately 18g. However, the lightest weights 14.48g and the heaviest weighs 20.90g and as far as I know holo doesn’t weigh 6g, haha. There’s no sign of any of the packs being resealed, so could it be a manufacturing mistake? There’s normally 10 cards per pack.
I’d love to hear your thoughts!
Error pack with all holo bleeds 
Aaaaaaah don’t tempt me with that!
I have a Japanese Base pack (from a sealed box) that weighs 19+ grams, when they usually weigh 16.5-17g. It’s full of Charizards and you can’t tell me otherwise.
Possibly resealed pack. I would be careful
Heck yeah! 
It’s a fair point! I’ve inspected it as closely as I can, and I just can’t see any sign of it being resealed! I’ll report back if I open it!
