The spiral notebook is A4 size (210 x 297 mm) and features a 0.8 mm opaque polypropylene cover. It has a continuous metal spiral that allows the notebook to lie flat and be turned easily. Thanks to the cover and the spiral, the notebook is durable and long-lasting. The paper inside has a weight of 70 g/m² and is extra opaque, preventing ink from bleeding through and drying quickly. The notebook contains 80 sheets with a colored strip on the side (matching the line color). The green lines include a header for titles and are grid-ruled with 5 mm squares. The sheets are micro-perforated for a clean tear and have 4 holes for easy storage.
