Hobonichi Cover Leather: Taut (Gray & Light Blue) (A6)

The Hobonichi Cover Leather: Taut in Gray & Light Blue is a close-fitting A6 leather cover that reduces the Techo Original (or Planner) to the essentials: slim hand feel, minimalist structure, natural cowhide. The leather bears the name "Seta" – derived from the Italian word for silk – and is refined by northern Italian tanner Poletto using the chrome tanning process, which gives it a slightly matte yet clear surface. Outside and inside show two different colors on a single piece of leather: warm gray on the outside, cool light blue on the inside.

Features

• Seta leather by Poletto (Northern Italy): Chrome tanning creates a slightly matte, silky smooth surface. The fine grain makes minor scratches barely visible in everyday use – the cover remains well-maintained even after intensive use.
• Two-color technology on a single piece of leather: Front side warm gray, back side cool light blue. Both tones are incorporated into a single piece of leather through a specialized manufacturing process – no assembly, no seam between the colors.
• "Taut" principle – deliberately minimal construction: No butterfly closure, no oversized pockets. The cover fits snugly around the book block and keeps it as compact as possible – ideal for a jacket pocket or small bag.
• Pen holder hook on the right: Designed for clip pens – works with slim ballpoint pens, slender mechanical pencils, or fineliner formats that have a clip.
• Interior slot pocket: Narrow card opening inside, suitable for business cards or credit/debit card format.
• Leather bookmark included: Small bookmark made from the same Seta leather, embossed with the Hobonichi logo in gold foil.
• Natural leather with individual character: Each cover bears the grain, veining, and texture of its animal hide – creases, veins, and slight color variations are characteristics of the natural material, not defects.

Use & Tips

• The cover fits the Hobonichi Techo Original (A6) and Hobonichi Planner (A6) – both book formats sit securely in the snug fit without play or looseness.
• The pen holder hook on the right side securely holds pens with a clip. Slim pens in triangular or round format – such as thin ballpoint pens or compact fineliners – work particularly well.
• The Seta leather requires no regular care with leather grease, but reacts sensitively to moisture: In case of dampness, immediately dab dry with a dry cloth and let dry in a shady, well-ventilated place. Never dry with heat.
• Dyed leather can transfer color onto light textiles or other materials, especially when wet or sweaty – take this into account when carrying in a trouser pocket.
• When new, the cover is still somewhat stiff and does not close completely flat: this will ease over time as the leather adapts to the book block.

For Leather Enthusiasts

Poletto's Seta leather is a European cowhide that is processed using the chrome tanning method – that is, using chrome salts instead of vegetable tannins. The result is a particularly uniform, dimensionally stable leather with a soft feel and low porosity, which is less prone to water spots than vegetable-tanned types. The two-color effect is not created by joining two pieces of leather together, but through a specialized dyeing process on a single hide – the color boundary runs down the middle of the cover and extends from inside to outside. With use, Seta leather develops a subtle patina: the surface becomes softer and takes on an individual, slightly more glossy character.
