I have used something like this on shorter trips https://images.app.goo.gl/tVSZ1G1vnLi8NYNKA
I think that most us have base weight that is low enough to have some luxury items like fresh eggs and beer on shorter trips.
The armour-plated egg box kept all six eggs safe until the third day, by which time it was empty. I then filled it with very small onions... and later with tortellini. Even though by then the rubber band keeping it closed had broken,* none spilt. Or split. However, on the morning of the sixth and final day, I found that the armour plating had come loose due to the dew softening the glue I'd used. I don't think its lack made any difference really.
*One of the friends I met up with promised me a whole bag full of ex-Royal Mail rubber bands... Gee, thanks!
On a recent Bavarian Alps trek my German walking buddy put me on to looking in supermarkets to purchase already boiled eggs; shells were coloured. It wasn't Easter when I think similar things are done over here to eggs.
