Well, I dunno. Guess we'll have to find out.
I've bought some long life milk in packs of six by 200ml tetra packs to go with coffee bags. I reckon it'd be OK to pack say, two per box, or three. That same shop also had some long life thickened cream which will probably go nicely with the bottled fruit I found.... and if it's not able to be cooled down they can maybe cook with it.
Then there's things like packet soups... cuppa soup things. I'd probably take off most of the box, even though it is only a few grams it adds up when you're talking only two kilograms.
What kinds of cooking additives would be handy?
I've found some toothbrushes for a buck each in packs of two, I think I'd send them in the two packs... they are toothbrushes! I'd like to find some small packs of toothpaste, too, just to go with the toothbrushes.
I just look out for specials and buy them, like a packrat... I've become a packrat. No, wait. I was always a packrat.
