Leather: Water Green A6 Original Size - Techo Lineup

LeatherWater GreenA6 Original Size

The graceful color is fresh as young grass and sprouts and has a sense of transparency like water. It is soft to the touch and feels moist and smooth. You can now have a cover with “butterfly-stopper” pen holders with the allure of Italian leather.

The leather used for this cover is called “SETA,” tanned by “Poletto” in Northern Italy. It is a slightly matte leather with a transparent feel, made from raw European hides and tanned with chrome. The name “SETA,” meaning “silk” in Italian, was given because of its silky touch and natural finish. This leather’s beautiful coloring and smooth, soft, and unique feel result from Italy’s unique sense of color. The fine grain also makes scratches less noticeable.

The interior pocket includes the Hobonichi logo in silver foil.

Every cover is unique and preserves the natural appearance of the original leather.

The Hobonichi Techo leather covers are made with all-natural materials that have their own unique appearance. Every leather cover is a one-of-a-kind, all-natural product, so you can feel good knowing your cover is the only one like it in the world. Here are some of the unique characteristics you can expect to find.

- Markings that naturally occur during an animal’s life:

Wrinkles, veins, texture, and scratches

- Characteristics from the manufacturing process of natural leather:

Dark spots (occurs when components of the leather are exposed to iron in the air during the tanning and dyeing process)

Leather with a clear and refreshing look

The color of this cover is just stunning, and the moist touch is so comfortable! We recommend this item for leather lovers and those interested in using leather covers.

The Italian company “Poletto,” which created this leather, has gorgeous colors in their leather sample books. We knew we wanted to create a cover with the light green leather when we found this exquisite color in the leather sample book.

We selected silver instead of gold for the “HOBONICHI” logo to match the clean and cool impression of the leather color. We also named the cover “Water green” for the same reason.

We hope you will enjoy the fine quality of Italian leather and the appeal of its fresh colors that will refresh your mind every time you have a look at it.

Please Read Before You Buy

We’ve compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Additionally, the color of the product may be slightly different in actuality than compared to how it appeared on a computer or smartphone screen.

About the pen hook: The pen hook of this cover is designed to hold a pen by its clip.

Leather may contain preexisting wrinkles and marks: In order to allow customers the enjoyment of all-natural leather, the leather is processed in a way that retains its original feel. This may leave imperfections visible on the surface of the cover, such as wrinkles, scratches, stains, or vein marks.
Depending on the conditions in which the cover is used, natural oils of the leather may emerge and appear as stains. We ask for your understanding for these naturally-occurring characteristics of genuine leather.

Color transfer may occur due to friction, pressure, or moisture: Color may transfer to other items through friction or prolonged contact. This risk increases when the cover is exposed to water or sweat, so please take extra care when carrying it near clothing or other belongings.
