Filofax A5 341664 interlayer refill is designed for Filofax A5 format calendars. It offers a set of thirteen interleaved sheets, each corresponding to two letters of the alphabet (from AB to YZ), in order to allow the alphabetical organization of the information, whether it be a "directory" within the agenda or a more specific ranking.

The cards are cream-colored, a particularly relaxing color for the eye, and the tabs with the letters are plasticized to resist manipulation. The Filofax modular system will allow you to insert these infill sheets where it will be relevant to you in the agenda, and to add sheets regularly between them, as information and notes
