@AccidentalEevee asks
this sleeve is so tight I'm scared to push the card in. Is snug supposed to be good?
Jeff answers
I'd stop before forcing it. A protective sleeve should fit the card safely, not require pressure on an edge. Check that it's intended for that card size and try an appropriate alternative. The accessory is replaceable; finding out how much force the card can take isn't a useful experiment.
