I have started taking my lunch to work more, and I can't find a box/bag that I like. Right now I'm just using plastic shopping bags, and I hate it.

I'm usually packing 1 or 2 bottled drinks, a Tupperware container or small frozen meal, and some sort of snack. So it needs to be a decent size, but I don't want anything bulky since I'm already carrying my purse and laptop bag as well.
