I have read all the posts and still have not found a suitable fold up aluminum or stainless cup. They are either too big or small. I can use wire from the kit to fashion a handle so that is not an issue for me...... any ideas. A small cup would be an asset worth having.

I only know of the collapsing cups made of concentric rings that you open like a telescope.There are a few sizes available through the re enactor outlets. Another option is simply a heavy duty, disposable aluminum cooking container.They can be folded into a relatively compact unit.

If I'm ever in a camping situation, I usually have my USGI canteen, cup, and stove with me at all times. If you don't wish to carry the old trusty GI canteen, I would suggest some heavy-duty aluminum foil to fashion a cup out of...all of the collapsable cups I've used didn't hold up so well.
