Ok so I have 2 CASES now coming from Tom (so much for only 4 boxes

) and Im just wondering how you guys store your rare cards like costumes, props autos etc? Is it safe to put them in plastic penny sleeves then screwdowns or does it damage the card? Just curious as these two cases are costing me $1500+ (AU) and I want to keep everything good.

Roughly what size cases are the latest prop and costume and auto cards fitting into? Anyone have an idea? Cheers for any help.
