Wallet Card Organizer

I need to be ready for file transfer anytime, everytime. The only thing I can think of is that I will always bring my wallet everywhere. All I need is a slim flashdrive that can put in my wallet without too much deform it. And Toshiba Onshu is my choice.
But after a while when I look into my wallet, its become
- 3 pcs Toshiba Enshu Flash drive
- 1 pcs unknown Flash drive
- USB to OTG adapter
- Kingston Micro SD reader
- Micro SD to SD Card

then I saw how unorganized this mess :)
