Hobonichi Pencil Board - ice gray x yellow A5

The Hobonichi writing pad "Pencil Board Ice Gray x Yellow" in A5 is a thin, precision-fit plastic underlay made from synthetic Yupo paper, designed to fit the Hobonichi Techo A5 Cousin. Ice grey as the base tone with a yellow grid printed on top – cool yet vibrant, without being obtrusive. Anyone who uses their planner daily and actually writes in it knows the problem: as the pages fill up, the block warps and the writing surface becomes uneven. This underlay solves exactly that.

Features

• Precision-fit for the Hobonichi Techo A5 Cousin (Cousin format, 215 × 147 mm) – sits snugly in the open planner without protruding beyond the edge.
• Yupo synthetic paper: 0.4 mm thin, yet rigid enough to create an even writing surface – even when the cover's inner pockets are stuffed full.
• "Today" tab at the corner extends beyond the planner block and marks the current page as a bookmark – no flipping, no searching.
• Front side: 5 mm square grid in yellow on ice grey – serves as a visual guide when dividing pages or freehand drawing straight lines.
• Back side: millimetre scale printed on, usable as a ruler directly in the planner – handy for segmenting daily pages or quick measurements.
• Protects Tomoe River paper: the underlay prevents impressions from ballpoints or fountain pens bleeding through to the pages below.

Use & Tips

• Slide the underlay under your current two-page spread – the "Today" tab then points upward out of the planner, making the page instantly findable.
• Those who write with ballpoints or fountain pens with broad nibs benefit especially: the hard Yupo surface provides even resistance for the paper, ink flows more smoothly and your line becomes cleaner.
• When laying out spreads – such as weekly overviews with multiple columns – you can use the yellow grid as an orientation aid without marking up the actual page.
• The printed ruler on the back is ideal for quick sketches, tables or measuring tape strips and washi tape sections directly in the planner.
• Also fits the Hobonichi HON, Day-Free A5 and 5-Year Techo in A5 format – not just the Cousin.
• If you stuff the inner cover with flyers, business cards or maps: the underlay compensates for the height difference and makes writing on the warped block pleasant and even again.

For Planner Enthusiasts

Yupo is not ordinary paper, but a biaxially oriented polypropylene film – it is completely water-resistant, tear-resistant and absorbs no moisture. This is why the underlay remains dimensionally stable even after years of daily use and does not warp. For Techo users who flip pages with damp fingers or carry their planner in a bag, this is a real advantage over cardboard underlays. The 0.4 mm thickness is roughly equivalent to two layers of heavyweight writing paper – noticeable, but not bulky when the planner is closed.
