How hard is it to move a DVD from a snapper to a keep case (Amray, etc.). I mean there is no pull out label. What do you do, trim the cardboard so it will fit in the sleeve, I guess? I bought enough keep cases to replace all my snappers and I'm thinking about doing it, but not sure how it will come out. I did move my ST II: TWOK Director's Cut, from the case it came in to a slimline double.
