One of my favorite binders is the Filofax Kensington. It is amazing on all levels.
- It is a vintage binder so very well made with fantastic rings
- It is soft and flexible with no stiffening
- It is perfectly designed for use as a wallet with plenty of credit card slots, a zip for coins and a nice pocket for notes
- Fairly easily available on eBay and sales groups
- Very reasonably priced – between €11 and €30
