One of the most popular and well-loved Filofax organisers, the Malden binders are made from lovely soft leather, with flexible covers that age beautifully. Available in A5, Personal and Pocket sizes, depending how much organising you need, and how easily portable you want it to be. With card pockets, and a zipped pocket, they're practical and versatile, and the Pocket size includes a wallet pocket along the whole cover, for carrying cash or receipts.
