Hobonichi Writing Pad Moomin: Mysterious Hat (A6)

The Hobonichi writing pad "Mysterious Hat" in A6 format fits perfectly in the Hobonichi Techo Original and protects subsequent pages from impression marks when writing. The material is Yupo – a smooth, slightly springy synthetic paper – that provides the pen with an even writing surface whilst feeling pleasant to hold. Both sides are printed: front features a scene from "Finn Family Moomintroll", back shows Moominpappa gazing into a mirror whilst wearing a magical hat.

Features

• Yupo synthetic paper (0.4 mm): The synthetic surface is dimensionally stable and won't warp with moisture – unlike paper or cardboard. This gives the pen consistent resistance across the entire surface.
• Protection from impression marks: Whether you're writing with a fountain pen, fineliner or ballpoint, the pad prevents indentation marks on the next day's page – particularly important with Hobonichi paper, which is very thin.
• "Today" tab: The rounded corner marker doubles as a bookmark: slip it between the current page and today's date is instantly visible.
• Millimetre scale on the reverse: A 1 mm grid runs along the long edge, useful as a ruler for small measurements – practical for pasting and layout work on your daily page.
• Two-sided design: Front features a Moomin scene from the novel "Finn Family Moomintroll"; reverse shows Moominpappa with the mysterious magical hat before the mirror.
• Precise A6 fit: Tailored for the Hobonichi Techo Original (A6) – sits flush without shifting.

Use & Tips

• Fountain pens and wet inks: Yupo doesn't absorb ink, and ink splashes wipe away without residue. The pad itself stays clean – even if the nib gets overtinged.
• Fine writing instruments: With fineliners (0.3–0.5 mm) or a fine to medium nib, the smooth Yupo surface writes beautifully – the pen meets consistent, light resistance without drag.
• Decoration and collage: When applying washi tape, stickers or ephemera, the pad protects underlying pages from adhesive bleed-through and provides a firm work surface.
• Bookmark function: Position the Today tab so it extends above the top edge of the book – then find your current page instantly when the Techo is closed.
• Ruler for daily use: For small cuts, aligning tape or measuring image sections, the millimetre scale on the reverse is often all you need.

For Techo Enthusiasts

Yupo is biaxially oriented polypropylene non-woven fabric – it has no fibre structure like paper, which means: no grain direction, no waviness with moisture, no soft edges over time. The 0.4 mm thickness exactly matches the Hobonichi Pencil Board standard and is calibrated so the pad doesn't add bulk when the Techo is closed. If you regularly write with water-based inks and value consistent letterforms, you'll appreciate Yupo's stable, slightly cool surface compared to soft cardboard – your line remains controllable, even during extended writing sessions.
