Hobonichi Cover Folio: Ocean Blue (A5)
The Cover Folio Ocean Blue is a sleek, bi-fold book cover for the Hobonichi Techo Cousin in A5 format. Both the exterior and interior are made from cotton – the cover sits soft and light in your hand without adding noticeable weight to your Techo. On the inside, a pen band is guided through a small leather patch made from cowhide: a fine handcrafted detail that makes a real difference in everyday use.
Features
- Sleek bi-fold design: The cover folds like a classic book jacket – no zip, no flap, no unnecessary bulk. Total thickness is just 3 mm, weight is 59 g.
- Pen band with natural leather patch: The integrated pen band is reinforced with a piece of cowhide and holds space for two pens of different widths – simultaneously, held securely, without slipping.
- Book band to prevent accidental opening: A dedicated band keeps the Techo closed so it won't open in your bag and pages won't fold.
- Cotton inside and out: The matt silk cotton surface resists fingerprints and develops a pleasant patina over time. Ocean Blue is a calm, medium blue with a subtle oceanic character – neither garish nor washed out.
- Perfect fit for A5 Techo books: Designed for the Hobonichi Techo Cousin (A5) – both January and April start editions fit in the cover.
Use & Tips
- Two pens, two widths: The pen band is intentionally designed for different diameters. If you, for example, use a thinner fineliner and a thicker mechanical pencil or fountain pen, you can securely carry both at the same time.
- On the go: At 59 g and 3 mm thick, the Cover Folio remains unobtrusive in small bags – your Techo won't rattle around loose, instead held compact by the book band.
- Pairing with pens: The leather patch on the pen band is durable enough for heavy brass pens or fountain pens with larger diameters without stretching or tearing easily.
- Caring for the cotton: Light marks on the cotton surface can be gently dabbed away with a slightly damp cloth. Avoid heavy rubbing on the surface to preserve the fabric feel.
For Techo Enthusiasts
The Cover Folio is deliberately designed without inner pockets or card slots – if you use your Techo as a pure writing and planning tool and want no bulk from credit cards or scraps of paper, you get a cover that delivers exactly that: protection, pen transport, closure. The cowhide patch on the pen band is not merely decorative: leather absorbs pen pressure differently than plain polyester and provides enough resistance to the pen so it doesn't immediately slip out when you pull it away. The polyester and rubber book band is elastic enough to securely hold even a well-filled Techo – for instance, with many sticky notes and inserted cards.
