Expand your ideas

More and more people use digital tools from the beginning when developing ideas. However, there are time lags and functional limitations in the process of selecting and inputting tools.
The hand is a tool directly connected to the brain. Nothing beats pen and paper for the sensation of directly expressing what you think in your head and getting immediate feedback. That stress-free situation is important for creatively expanding your thinking and formulating ideas.
However, if you keep a notebook or a sketchbook as a journal, you will quickly run out of pages. It is also difficult to delete unneeded pages and to store them. In the end, many of you may have hesitated to write in your notebook or sketchbook and never used up the last page.

We wanted to make it easier and freer.

The Hasamu® A4 was born to fulfill this desire.

Aria" is as light as air.

Aria" means "air" in Italian. It also means a lyrical solo song in opera and religious music.
Like air, you forget it even exists. Yet, it is beautiful and full of originality.

Highest Quality Manufacturing Process

All parts of the Hasamu® A4 Aria are made of thin leather glued on all sides. This is the most luxurious technique for leather products. Two thinly stripped pieces of leather are pasted together to create a stronger, lighter, and thinner finish. It takes a great deal of experience and skill to create a finish that gives the illusion of a single piece of leather without lifting or flexing even when folded.
To enhance the writing experience, the interior is made of fine, soft, smooth leather.

The finest details

The simpler the design, the more important the details.
The outer edge of the leather is stitched just barely wide enough, and the leather is carefully polished and beautifully finished after dyeing.
Etretat spares no effort in polishing the leather to enhance its durability and beauty, in pursuit of the highest level of detail.

Just insert A4 paper

A4 paper, the most common standard, can be inserted between the two pockets. Simply insert both ends of the paper into the pocket.
There is no need to fold, punch holes, or do any other troublesome work.

Half the size, carry smaller.

You never know where an idea will strike. That is why it is important to make it easy to carry. Folded in half, it can be carried in A5 size, and opened to a flat A4 size, so it can fit in a small bag that does not hold A4 documents.
Pens can also be set in it, so there is no need for a pen case.
It is crease-resistant and can be used as a document case.
(Strong pressure will leave a crease.)

Big and comfortable

A large, seamless surface is important for expanding your ideas. The pockets on both ends are minimally sized, and there is no crease in the center, allowing you to make great use of the paper.
Comfort is also important for your patronage.
The flat design with no extra parts or bumps allows you to enjoy the smooth writing experience of a leather desk mat.

You can choose your favorite paper.

You can use any type of paper: graph paper, manuscript paper, ruled paper, blank paper, and loose-leaf paper. The
A4 size makes it easy to print. You can find ruled paper, graph paper, calendars, and various templates on the Internet.

Free original templates are also available, such as for perspective drawings.

We recommend lined paper. Not only is it environmentally friendly, but you can also write whatever comes to mind without worrying about the number of sheets, making it perfect for brainstorming ideas.

Flip and browse.

You can flip the paper between one side and the other to browse and present it like a book.

Minimalist design

The body, pen holder, and paper holder are all made of one smooth, continuous piece of leather.
When closing, the pen clasps directly to the pen holder, which is held securely in place by a three-stage butterfly stopper, preventing the pen from losing its shape.
The pen holder is large enough to protect your favorite pen from scratches. Pens with a diameter of approximately 10mm or less can be used.

Save it as is when you are done writing

When you are finished writing, you can file the necessary paper or save it to the cloud. The A4 size is easy to handle, and since it is crease-resistant, scanning with the ADF is smooth and free from paper jams.
