1. My ebook reader
2. At least one physical book
3. Pencil case full of pens of various colours
4. Small medkit (band-aids, antihistamine, paracetamol, alcohol swab)
5. Reusable cutlery
(I have two bags, one which is more like extra pockets and I cannot fit too many things in, the other is for when I'm going further than just a quick run to the store... I am also not including all the receipts I somehow never throw away until I gather a whole bunch of them and then I'd stress over whether I should throw them away)
