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. |
