OTOH, sometimes small and compact is a good idea.
Something like this : http://www.survivalmetrics.com/store...y_survival_kit
- 6 x 6 x 2.5 inches, 14 oz, small enough to fit in a cargo pocket if your work allows that kind of casual dress - might work for a with-you-ALL-the-time kit. (It's still a bit of overkill for walking home - not a lot of likelihood one might be fishing or trapping food - and is missing food and an actual water bottle - but wouldn't fit in a pocket if it had those; trade-off.) These days, I kind of expect EDC pocket knives and a flashlight outside emergency kits.
A bit expensive, I think.
Madoka, where are you getting your med supplies? I bought some stuff through Amazon, and some from https://www.shopmedvet.com/
