How to tell holofoils in a pack of yugioh cards?
take two packs and bend them if one of them is harder than the other that means theres a holo in it but if both bend the same and is easy to bend then both dont have any


just well


take 2 booster packs


if one of them is harder to bend then then there s a holo


but if they feel the same just switch the 1 booster pack to another














or u can try the freezer trick





if u have more than one booster pack and u want to know if there is one put them in a freezer 4 like an hour and check how fat it is
