The FC-3 filter case is an "Accordion" case that holds five filters in padded sections, all clinched securely with an expandable strap. The handy pocket across the front has room for filter tissues, and a small bottle of cleaner. A see-through window on top allows quick reference of notes.
The filter case comes with a belt loop for carrying it on the waist. (For expanded capacity one or two extra add-on sections can be purchased and simply placed in unit with Velcro fasteners.). Holds filers of size up to 4" x 6".
