This is a cover with “butterfly-stopper” pen holders made of classy, deep yellow leather. The Italy-made leather is soft to the touch, and the fine grain on the surface creates contrast and depth.
We named it “Brilliant” Yellow, hoping the user’s year will be full of happiness and brightness like the overflowing light.
The leather for this cover is “Dollarino,” a chrome-tanned leather produced by Monfrini Pellami. This long-established tannery, founded in Milan in 1898, has produced four generations of leather for fashion and accessory items. The leather is characterized by its touch, volume, and beautiful coloring unique to this traditional Italian tannery.
The interior pocket includes the Hobonichi logo in gold foil.
Each cover has its own unique take on the texture and character.
In the Hobonichi Techo 2025 lineup, the Cousin book comes in either English or Japanese.
*The English book is only available as the January-start version.
The Hobonichi Techo leather covers are made with all-natural materials that have their own unique appearance.

In order to provide you with the most satisfaction for your product, we've compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Please be sure to read this information carefully before placing your order.
Each item is individually assembled and sewn by hand by a factory worker. Best efforts are made to ensure consistent sizes and specifications, but there may be slight differences.
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.
Dyed leather products tend to leave stains. Please be careful not to allow the leather to adhere or rub against other objects such as clothing or other belongings, especially if the bag is wet from water or sweat from your hands.
Immediately dab your product with a dry cloth if it gets wet. Avoid drying it with high temperatures, and place it in a well-ventilated place in the shade.
The PVC plastic of the Cover on Cover contains plasticizer additives which may cause a reaction in the leather dye and affect the color and quality of the leather cover. Please refrain from using the Cover on Cover with this product.
Please avoid storing your product in hot, humid places or placing it atop other objects for long periods of time as this may result in lower quality and color stains.
During the leather drying process, particles floating in the air may adhere to the surface. Please understand this is an unavoidable part of the production process.
If you’ve used any of these products, we welcome your notes on what you like about them or what led you to buy them so we can share it with customers who are currently considering these products. We’d also love to welcome comments from customers who purchased their techo outside the Hobonichi Store or received their book as a gift.
