These Case Logic CD-i disc holders have slipcases for 48 CD-i's, often used by Philips to store CD-i demo's and testing discs

CD-i member Arethius RGC spotted this Case Logic CD-i holder, like we've seen often before in various CD-i sets full of demo discs and prototypes. I guess Philips themselves had a lot of these, I never saw them in the shops. This version holds 4 CD-i's per page, offering space to a total of 12x4=48 CD-i discs.
