I have a well taken care of SFbags sleeve case for an ibook 12"
looking at the specs here: sfbags sleevecases
it looks like the powerbook 12" will fit, but it'll be a tad looser.
the ibook fits tight in this bag.
holy cow that is outta focus!

the cheapest you can get this bag new for is $43 (38+5 shipping, or $8 for priority)
the bag is in great shape, black with a silverish bottom.
I'd like $33 which includes ground shipping. or something in that ballpark.
private message me or post here if interested.
