I see a bunch of EDCs out there for other people’s emergencies (“bring tylenol in case someone has a headache” type of advice). I simply hate the idea that you’re responsible for preventing \*everything\*. so, my rule is simple: if I’ve ever found myself wishing I had something, I have added it. 

  
I live in a big city, so if I ever really need water or a painkiller I can buy it, no problem. what I do have is type 1 diabetes and wear a pump and a sensor, so I need a couple extra things. I’m also really eco-conscious and try to reduce waste. I have foregone some single-use items and created reusable options  

  
from top to bottom, left to right:

TOP

* keys with 4 glucose tablets in an aluminium case 
* makeup remover wipe (I bought a travel size and cut it further into quarters, as opposed to single-use sheets): sometimes my makeup gives me allergies and I need to remove it ASAP 
* eyedrops decanted into a mini glass dropper (as opposed to single-use tubes): for my allergies
* sunblock samples
* AA battery: for my insulin pump
* alcohol wipes: great for disinfecting surfaces or hands (substitutes hand sanitizer)

MIDDLE

* emergency whistle
* mini flashlight 
* swiss army knife (with scissors, blade, nail file, screwdrivers, can opener, toothpick, and tweezers)
* mini pencil (worn down from use)
* lip balm that can also be used as ointment or moisturizer (attached to my keys)
* medical cloth tape: for my glucose sensor if it becomes unstuck. it is really good as a multi-purpose adhesive as well
* hair tie
* safety pins
* moisturizer sample

BOTTOM

* power bank
* bag with wired headphones and charging cable: I hate being stranded without my earphones
* money wrapped in a plastic bag
* bamboo spork wrapped in a paper tissue: in case I get coffee or eat something where only plastic cutlery is available, I can use mine
* wet wipe in a tube (took a bamboo wipe and tolled it, boiled it for 7 minutes, put it (with boiled tongs) in my aluminium container—I wouldn’t treat it as sterile, but at least there’s nothing growing in there when I need to wipe something)

  
this all fits in a mini Muji nylon bag, except for my keys. the knife dangles outside because I use it regularly. my purse also has a small spray bottle with alcohol (instead of hand sanitizer) and reusable carry bags.
