A bound collection of leaves having a spine and a method of its manufacture are disclosed. Each leaf of a first plurality of leaves of the bound collection includes a first pattern of tabs by which that leaf is bound. The tabs of the first pattern are distributed along a binding axis of that leaf that is parallel to a spine axis of the spine. Each leaf of a second plurality of leaves of the bound collection includes a second pattern of tabs different than the first pattern by which that leaf is bound. The tabs of the second pattern are distributed along a binding axis of that leaf that is parallel to the spine axis. Each tab of the first pattern and second pattern of tabs extends in a direction orthogonal to the binding axis from within an unbound region to a binding-side edge of that leaf.

A fact sheet for insertion between two pages of a notebook, the notebook pages being bound by a spiral binding. The fact sheet includes a sheet having two generally parallel sides and, along one of the sides, a row of perforations into which the coils of the binding can be inserted to removably secure the sheet to the coils. The row of perforations includes a uniform alternation of oblong perforations and narrower perforations that are narrower than the oblong perforations. The alternation has a period including an oblong perforation and a narrower perforation, which are adjacent and consecutive. Each oblong perforation is shaped to receive either one coil or two coils, depending on the separation of the coils of the stationery product, and each narrow perforation is shaped to receive a single coil.

The present invention applicable to the technical field of stationery provides an erasable drawing notebook, which includes a cover, a back cover and connection rings. At least one middle page is arranged between the cover and the back cover. The cover, the back cover and the middle page are binded in series via the connection rings. An erasable writing area is arranged on the middle page, and a first storage bag is arranged on the cover surface. The erasable drawing notebook can be repeatedly used for activities such as writing, drawing, and painting, etc. Besides, users can store items in the storage bags to avoid loss of items.

A bound collection of leaves having a spine and a method of its manufacture are disclosed. Each leaf of a first plurality of leaves of the bound collection includes a first pattern of tabs by which that leaf is bound. The tabs of the first pattern are distributed along a binding axis of that leaf that is parallel to a spine axis of the spine. Each leaf of a second plurality of leaves of the bound collection includes a second pattern of tabs different than the first pattern by which that leaf is bound. The tabs of the second pattern are distributed along a binding axis of that leaf that is parallel to the spine axis. Each tab of the first pattern and second pattern of tabs extends in a direction orthogonal to the binding axis from within an unbound region to a binding-side edge of that leaf.
