Designed by the pen community's own The Well-Appointed Desk and brought to life by Skylab Letterpress, this booklet is the perfect tool for testing and cataloging your ink collection.

The paper—made by a 400-year-old European mill—was rigorously tested to ensure that inks would not feather, bleed, or show through. The paper is lightly textured and safe for use with even the sharpest nibs. The paper is protected by sturdy chipboard covers with stylish letterpress printing and held together by a handy binder ring, letting you remove and reorganize the sheets whenever you want.


  • 100 sheets.
  • Thick, ink-friendly 100 lb (160 gsm) acid-free paper with a slightly toothy texture.
  • Suitable for use with fountain pens, dip pens, brushes, and cotton swabs.
  • Sturdy chipboard covers.
  • Binder ring for easy removal and rearranging of sheets.
  • Designed and manufactured in the USA using European paper sourced from a local distributor.
