Here's what I store in mine:
The Makeup bag /pencil case- I use this damask print pencil cake from Tesco of all places, spotted on a usual stroll down the stationery isle during the family grocery shop. I've used it as a pencil case and now I think it better serves as a prettier makeup bag/ bag organiser. Besides it's definitely too pretty to get ink stains on.
The products- Made up of minis my bag contains a lipbalm, hand sanitiser, and a perfume- for them 'emergency' situations, of course paracetamol and a mirror for the vanity of it too!
The backup supply- Now we can go even further in technicality and say that this bag-ception goes to another level with this mini pouch I keep small items in. Safety pins, hair ties/ grips, money too. Even though I have a purse in my bag I keep exactly £2.40 in the pouch for the day I might loose my oyster card and have no real change to purchase a ticket on board.- No body likes the people who hold the bus up counting their pennies.
Extras- If I'm wearing lipstick or liquid eyeliner then I carry them with me for touch-ups because sometimes you just gotta! And how can I forget the obligatory Haribos!- I'm always peckish at the wrong times!
If you have a bag organiser or 'survival kit' in your bag what do you keep in there?
