The four treasures of study are the cultural treasures of China. But with the development of science and technology, more and more people have little touch pen and paper after leaving campus. People are more accustomed to the keyboard and voice of fast typing. Sometimes they can calm down to write what they have in mind, so that they can better understand their true self. Thank you this time Love to play computer games Try Elfinbook's latest repeatable writing package.

First, let's take a look at the outer package. It is very simple in design, without too much fancy content. It directly lets you see all the functions and features, simple and clear. It's my favorite style.

Thank you for the opportunity to try out the computer.

The back is even simpler. A QR code can be the company's address name. The packaging box is really very simple. Let's see what's on your back!

Everything is here, a notebook, a pen eraser, an app VIP code, and a manual.

The manual briefly introduces the use instructions, and lists the centralized erasure methods, which will be tried one by one later.

Vip code, which can be upgraded to advanced users. Some commonly used recognition apps will be compared later.

The logo on the cover of this book is designed very well, which is interesting.

This book adopts the design of a coil book. The fixed page type cannot replace the inner page. After writing, the inner page cannot be replaced. The cover is made of PVC, which is wear-resistant and not easily damaged. The inner page can be well protected as a horizontal line, with a row height of 7mm. There is a dot matrix on the horizontal line, and the spacing is also 7mm. It is convenient to check and draw charts, which is more practical. And the coil book can be opened 180 horizontally, or the previous page can be folded back, which is convenient for writing. Unlike the fixed page book, it can not be flattened, nor can it be blocked by the middle coil like the loose leaf book. The paper is made of stone. After treatment, it feels very soft. It is different from common paper, just like the paper is wet by water.

Let's take a look at the erasable pen of Baile. It was a super famous product launched by Baile at that time. It can be erased and rewritten at will, and will never mess up the book again. I have a push button model. Elfinbook comes with a hat pulling model.

The tail of a hat pulling book is a rubber head, which is used to erase writing marks.

Because of the characteristics of the pen, the pen is also labeled with notes. Some Chinese documents and signatures should not be used. It's very considerate to remind you.

Daguo has bought the erasable pen, push type and three color versions of Baile before. The three color version is really expensive, and the refill is not cheap at all. Find some pens for writing test. After all, as a notebook, the feeling of writing is also very important.

First, let's write a test, pen, neutral pen, all together. To be honest, the writing feeling of this paper is too comfortable. Very smooth, no matter which pen it is, very smooth. Never hang paper with a pen.

Take a look at the back. It's not transparent at all. It's cool! If you often use a pen, seriously, it's worth a try.

Use a video to see the erasure effect. Use the rubber head, hair dryer and hot water to test.

From the above video, it can be seen that the rubber head is easy to use when taking notes. When writing wrong words or drawing needs to be redrawn, but it is troublesome to wipe a large area clean. Then use a hair dryer, which is very suitable for large area elimination. When using hot water, pay attention to the water temperature, which is basically above 50 degrees Celsius, This method is seldom used. The water temperature is too high and it is easy to burn.

Paper soaked directly in water is not as easy to break as ordinary paper. It is still very strong. I dried the paper and found that it can still be used... It's really good paper. Except that the handwriting can be easily eliminated, its waterproof performance is very good.

Let's take a look at the performance of the app. In fact, there are many such apps. The earliest all-around scanning king, and the impression notes are also from Apple, but they use a lot of Offie Lens, which has a single function and no additional functions. It is very easy to use, single function, but professional.

You can see that the edge can be automatically recognized after taking a picture, or you can set it yourself. Press and hold the dot on the four corners to enlarge the image for precise selection.

After recognition, it can also be adjusted. There are three modes: enhancement, black and white, and original image. In addition, it can also adjust the contrast and brightness. This is an additional adjustment function than Lens.

To see the effect, there is not much difference between enhancement and black and white mode. They are all default settings, and the contrast between black and white is more obvious.

Let's take a look at the effect of Lens.

The contrast of Lens is not very strong. The texture of the original paper is well preserved, but not removed because of the effect. Elfinbook's app pays more attention to the embodiment of content. Black and white contrast is strong, and I think they have their own characteristics, so I can choose according to my own needs.

In conclusion, Elfinbook's stone book is very good. Because of the material, the writing experience is very good. The quality of the paper is also very good. It has good toughness and is not easy to damage. It is very suitable for long-term storage. For those who like to write accounts by hand, it is worth recommending. After all, the paper made of traditional pulp will slowly deteriorate after time, This paper should be better kept as it is, but some people may prefer the yellowed paper with more signs of age, which shows their own needs. But this paper is really easy to write, but its price is slightly higher. However, this paper made of stone is very rare. If you want to reuse it, it seems not very good, The notes can be eliminated, but the traces will not be eliminated. The paper will become very ugly. There is nothing to say about the erasable pen, that is, adding other raw materials to the fuel, and then eliminating the traces through temperature. The usability of the app is also good, and the effect is relatively obvious. The notes are very clear, and the user's habit of using the app depends on the user himself. I hope we can develop more paper of various materials. First, we can make paper with distinctive characteristics. Second, we can no longer use wood as raw material and protect the environment more. This Elfinbook is a four-star recommendation.

Advantages: good paper, good sense of writing, rich app functions

Disadvantages: slightly higher price
