The Leuchtturm1917 notebook fits 305 477 because of the thin, soft but not less noble COVER well in the pocket. Where a firmer cover interfere and the trouser or jacket pocket would bulge, it clings to itself and is hardly noticeable. The booklet has to keep a complete equipment with page numbers, table of contents, a bookmark, a practical, slightly retro rubber band around it closed and a pocket in which similar to list can be stowed. The present version of me with blank pages is more suitable for sketches because for notes; when using a soft pencil the right thin paper does not interfere. However, when pen or even a fountain pen used, the font / ink proposes unfortunately mercilessly through the thin pages. Here somewhat thicker paper would have brought a better result.
Conclusion: For sketches with a soft pencil in order, unfortunately problematic in more vigorous writer.
