AvoK95 wroteAren't they just blu-ray cases?
PS4 cases are not the same as PS3, or even Blu Ray cases, in that, the plastic cling goes all the way up the case, and the artwork is also "all the way up"( PS4 cases are 14mm thick, single disc )
maybe you could get a quality 14mm double case and just remove the second disc "flap"
