@SlabConfused asks
dropped a top loader and the sleeved card slid out. Should it have been sealed somehow?
Jeff answers
I'd use a suitable outer bag or closure that stops movement without putting adhesive near the card. Check the fit of the holder too. Protection works as a system, not just a rigid piece of plastic. Before carrying cards, gently check that they stay where you put them.
