A world-renowned filing solution, this European A4 binder features a patented lever-arch design that opens its unique U-rings effortlessly, at the touch of a finger, to a full 180 for easy contents management. A slotted-cover design and ring-lock mechanism keep the binder closed and standing upright when filed away. Rigid pressboard construction with metal-reinforced edges and a finger-grip hole on the spine delivers the perfect balance between durability and quick-pull convenience. Each binder's self-adhesive spine label enables easy indexing. Standard 8 cm ring spacing.
