I have heard from the old people since childhood that "a good memory is not as good as a bad pen" and "the lightest ink is better than the strongest memory". It is true that no matter how good a memory is, it is inevitable to forget it sometimes. Therefore, some important things should be recorded firmly. However, there are occasional mistakes when taking notes. Generally, we will choose to erase or rewrite them directly. However, this will not only waste time, but also waste a lot of paper, virtually increasing the environmental pollution. At this time, we need a notebook that can be written repeatedly. Next, I want to introduce a smart notebook that can be written repeatedly launched by Qihui Technology - Elfinbook.

Let me first briefly introduce today's protagonist "Elfinbook Repeatable Writing Notebook".

ELFIN BOOK is made of stone paper, waterproof and durable, and can be repeated for about 10 times with erasable pen ELFIN BOOK It can be used together with the supporting APP to achieve powerful document management functions.

Unpacking appearance

ELFIN BOOK's rewritable notebook is packed in a popular white paper box, and its surface is wrapped with a layer of plastic film. The first thing that comes into view on the front is three functional patterns of APP software, with the product name on the top and the highlights of the product on the bottom: made of stone, smooth writing, waterproof and durable, reusable, automatic scanning, note enhancement, cloud backup Document management.

There is a QR code on the back. You can download the ELFIN BOOK APP by scanning the QR code. Below is some information about the manufacturer.

I can't wait to open it. First, I tear off the plastic film on the outside of the package. As the "machine trial" sign is pasted on the package film“ Love to play computer games ”The hardcore fans still carefully removed them from the packaging film and pasted them on the outer packaging as usual.

The package contains, ELFIN BOOK rewritable notebook * 1, Baile erasable pen * 1, instruction manual * 1, letter of thanks * 1.

The ELFIN BOOK repeatable writing notebook has two colors: black and deep space gray. This time, the color we got is deep space gray.

The cover of ELFIN BOOK rewritable notebook is made of pp, which is waterproof and durable.

ELFIN BOOK Repeatable Writing Notebook is made of 40 pieces of 170mm × 250mm stone paper, which feels like a kind of skin texture.

ELFIN BOOK is bound by punching and pressing rings. From the perspective of workmanship, Elfinbook has very professional binding technology, and there is no risk of scattering.

From the perspective of the clarity of the grid, the printing quality is also very good. Personally, I think it is quite professional.

ELFIN BOOK Repeatable Writing Notebook is equipped with a neutral pen produced by Pilot. The difference between this pen and ordinary neutral pen is that the end of the pen holder is like an eraser head. The writing can be erased through the rubber eraser at the end of the pen, which is convenient for modification.

What is worth mentioning most is the letter of thanks written by Elfinbook project team to users. The letter of thanks can show the sincerity of Elfinbook project team.

The VIP exchange code is on the back of the letter of thanks. After registering and entering the exchange code, you can try all the functions of the APP for free.

The next poem is very well written, and it reminds me of some past events in my school days.

experience

It is understood that stone paper is a new material between paper and plastic, which has the same writing performance and printing effect as plant fiber paper, and has the core performance of plastic packaging. The product has the characteristics of good mechanical performance, waterproof, moisture-proof, moth proof, folding resistance, tear resistance, oil resistance, non-toxic, tasteless, pollution-free, stable geometric dimensions, high printing clarity, good effect, and can be naturally degraded into powder after use and returned to nature.

Did you see? The notebook has been written as a notebook, which is not intentionally wrong. It has not been written for N years, and many words have not been written. The font is also very ugly.

Wipe it with the pen cap's own rubber eraser.

It is obvious that the efficiency is not very high. The whole erasing process is a strong friction and then generates high temperature to make the writing disappear. This method is only applicable to the erasing of single words.

The effect of dipping toilet paper in water is very obvious, and the wiping is also very clean, but the traces written are very obvious.

Next, use a hair dryer. It cleans very quickly. I feel that using a hair dryer is the most efficient.

APP function and experience

The software adopts machine vision and image processing algorithm, which will automatically find the frame of the notebook and then cut and straighten it.

The generated file can select three image effects: enhancement, black and white, and original image.

If the border recognition is wrong, you can adjust it manually.

The software has a search function and supports keyword search, which is very convenient and fast to find.

PDF documents can be shared with friends through WeChat, QQ, etc.

A few drops of water on the notebook looks like a drop on plastic. It seems that the waterproof performance of ELFIN BOOK reusable notebook can also stand the test.

In general, Elfinbook reusable notebook is very secure both in the binding process and in the quality of printing, and the waterproof effect of the notebook is also very obvious. At the same time, ELFIN BOOK uses very environmentally friendly stone paper, which can be reused for many times in use, and can save a lot of wood. It is low-carbon and environmentally friendly. If it can be popularized, Undoubtedly, it can provide great help for protecting the natural ecological environment. The APP is simple, convenient and convenient to operate, and supports fast search and search of document titles, which is very consistent with the fast-paced lifestyle of modern people.
