[vcf-midatlantic] Commodore Fans - what is this case for?

[John Heritage]

I have a soft case for a commodore product, that I inherited when picking
up a bunch of Atari stuff from a friend.   What is this for?

It's not very thick - so I don't think it would fit any kind of a floppy
drive, but I may be wrong..   similar 'feeling' as to whether it would hold
a casette player for the c64 or something..

Anyway I'd appreciate any knowledge on this :)
