I'm shipping out four of these to PSA. Local dealer has nothing usable and can't to justify purcahasing something elaborate online. I was thinking a ziplock bag then the cardboard sandwich. Any clever, crafty ideas?.. (They're lower grade.)

They'll fit into graded card sleeves (the sleeves people sometimes store a graded slab in). Just cut off the flap with the adhesive strip at the top. These are cheap and easy to find. Then, just stack the 4 cards together, throw a piece of cardboard on each end, tape it together and off they go.
