It's undoubtedly been discovered previously by about 30 thousand other people. But for any who are still grappling with the serious question of how to carry snacks around in a purse, tote bag, or briefcase, even long term, without their getting smushed or crushed -- I offer my solution: the hard, spring-hinged eyeglass case.
A hard case accomodates candy and snack bars or even those preservative-laden, yet fragile, cracker packs, and will preserve them from all hard-to-eat or unappetizing mutilations, even if kept in the purse or bag long term.
That's about as high as my mental biorhythm will let me soar today. Carry on, Grasshoppers.
