Minimalist A4 case to expand your ideas
(Design registration applied for)
Hasamu® A4 is a tool to carry half the size of A4 paper and open it to write freely, to expand your thinking creatively, and to develop your ideas.
A Tool for Expanding Ideas
The impetus for the development of this product was the desire for people to use a tool that allows them to think freely. More and more people are using digital tools from the start when formulating ideas. However, there are time lags and functional limitations in the process of launching an application, selecting a tool, and inputting information.
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 jot down ideas as they come to you in a notebook or sketchbook, you will quickly run out of pages. It is also difficult to delete unneeded pages and to store large quantities of them. In the end, many of you may have hesitated to write, and not even used up the last page.
More easily, more freely.
The Hasamu® A4 was born to fulfill this desire.
Effective use of the paper backing
Another motivation for product development was environmental measures. Hasamu® A4 was created to make effective use of waste paper backing.
However, when we actually started using the product, we made an unexpected discovery. Regular A4 paper is versatile and convenient, but with lined paper, you can freely write anything you want without worrying about missing anything or the number of sheets at all.
To develop ideas, it is important to be able to write without stress. Effective use of lined paper is one of the best options for this.
Just insert A4 paper.
You can use A4 paper, the most common standard, between the two sides of the paper. Simply insert both ends of the paper into the pocket.
There is no need to fold, punch holes, or do any other tedious work.
Simple structure of just inserting paper
Half the size, small to carry.
You never know where an idea will strike you. 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.
It can also hold pens, so there is no need for a pen case.
It is crease-resistant and can be used as a document case.
(If you press too hard, a crease will remain.)
Size comparison with an A4-size notebook computer
Big and comfortable
To expand your ideas, you need a large, seamless surface. Minimally sized pockets on both ends expand your writing area and allow you to utilize paper without waste.
In addition, comfort is important to use the product well with love.
The flat design with no extra parts or bumps serves as a smooth writing leather desk mat.
Minimally sized paper pockets
You can choose your favorite paper.
Square paper, manuscript paper, ruled paper, blank paper, loose-leaf paper, and lined paper. The
A4 size makes printing easy. 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.

Flip and browse
You can flip the paper and browse it like a book by inserting only one side.
Presentations can also be made by inserting materials between the two sides.
Minimalist design
The body, pen holder, and paper holder are all made of one smooth continuous piece of leather.
No hardware is used at all. The pen clasps securely and prevents the pen from losing its shape.
The pen holder is long enough to protect your favorite pen from scratches. Slim pens with a diameter of approximately 10 mm or less can be used.

Careful detailing
The simpler the design, the more important the detail.
Fine lines (nen) are carefully placed around the perimeter, and the leather cross section (koba) is carefully polished and beautifully finished after dyeing.
The floor (back side) of the leather is also carefully polished to minimize fluff and unevenness.
Careful finishing of the koba
Save your writing when you are finished
When you are finished writing, you can file the necessary papers or store them in the cloud. The A4 size is easy to handle, and the crease-resistant design prevents paper jams when scanning with the ADF (Automatic Document Feeding) function, making scanning smooth.
