Just bought a new case for my digital camera, but unfortunately it
doesn't have the useful little zipper pouch to contain 2 spare AA
batteries that my old (lost) case did. There is, however, just enough
space within the case for the spares, but obviously without protection
they'd rattle around damage the camera.

I'm trying unsuccessfully to think of something readily obtainable I
could stuff them both inside, to hold them firmly together - something
along the lines of a bit of compressible foamex or rubber tubing, say?
But can't come up with anything better than the unsatisfactory bit of
cloth the batteries are currently wrapped in.

There are plenty of hard-ish plastic cases for 4xAA cells - if there was
a similar case for 2, that *might* just work...

Any creative ideas welcome!

Thanks
