Soggy-bread lunch boxes are a real thing: get one with compartments
Yes, lunch boxes that keep bread from getting soggy are basically just boxes with separate compartments for wet stuff. No special technology here—just physical separation.
The usual design is a bento-style box with fixed dividers, like Yumbox, Bentgo Fresh, or LunchBots. You put the bread or assembled sandwich on one side and the tomatoes, pickles, or sauces on the other. Some boxes take it further with a little removable tray or dip cup so wet ingredients stay even more isolated. At lunch, you assemble the sandwich right before eating.
The box helps, but the strategy matters more: drain pickles, dry off tomato slices, and store condiments separately. Any container with a divider or a small sauce cup inside a regular lunch box will do the same thing.
Future you deserves a crisp bite, not a wet one.
