Topps Comics

I just bought 2 Lebron James rookie cards. I want to put them in the 4 corner screwdown cases. Which are best?

I’ve seen some called Ultra-pro, and BCW. The ultra mold ones claim to be acid fee, and contain no PVC. The BCW ones are polystyrene. I really don’t know what or what doesn’t make something acidic. I know cardboard can turn things yellow, and I know newspaper (my dear old comic books) turns yellow, but that’s the extent of my knowledge. I guess the old topps baseball cards were pretty much straight up cardboard. Any tips on how to keep Lebron happy? (Besides getting him another big forward and a shooting guard

For my sports cards I keep the more valuable ones in thick plastic cases.
