Erik, I have used CardSaver Is and have my '53 Topps baseball set (the ungraded portion) stored in them. I actually have the '53s in penny sleeves in the CardSavers....I know that was redundant and unnecessary. I am a little OCD I guess
. Lately, I have opted for the toploader/penny sleeve combo, like with my '65 baseball set and this '69 football set. I honestly like both.
I didn't realize how much I like that '69 set until I saw it in person. I am hooked! Looking forward to adding more sets in 2016!
