Gym challenge heavy weight

Hi, how much should the booster packs from unlimited gym challenge weight approximately?

Check here

I have 3 at 20,94-21g so I consider them as heavy taking the amount of cards into consideration :blush:

Can weigh as low as 20.70 up to 21.2 (that´s what I opened personally from boxes)


I actually don’t have a scale that measures decimals and only weighed one pack and it showed 21 grams haha so that one should be heavy for now, right?

Thanks for the answers, I’ll now do a better job weighing them
