Set storage question

[bblair_2002]

Hello all. I was thinking about transferring some of my refractor sets from penny sleeves inside shoeboxes to a binder and sheets,but I'm afraid the cards may warp over time. Has anyone experienced this when storing your chrome or refractor sets? Just looking for feedback on what I should do.

Thanks,
Brett

Bowman Chrome Prospect also has the curling problem.....I always place them in plastic sleeve and into a top loader. Only cards that go into just plastic sleeves are base sets of topps 1, 2 and updates. Best regards, David
