An exclusive accessory for the classic Delphonics Rollbahn notebook. This underlay can be attached directly to the Rollbahn notebook, providing stability and smoothness during writing.

The clear material allows the contents of the page to remain visible. The top hook attaches securely to the ring, while the bottom fits into the hole for firm placement. The printed grid and ruler markings add both practicality and convenience.

Equipped with a pen holder that accommodates thicker pens, the underlay can also function as an index tab, enabling quick access to frequently used pages.

Available in three sizes: M, A5, and L.
