Recently, I came across a new gadget - stone paper. I will introduce it to everyone at the beginning (ask Du Niang).

Stone paper is made of limestone mineral resources with large reserves and wide distribution as the main raw material (calcium carbonate content is 70-80%). After special processing, it is made by polymer extrusion and blow molding processes.

Stone paper is a new material between paper and plastic, which can replace some traditional functional paper, professional paper and most traditional plastic packaging. It has the characteristics of low cost and controllable degradation, which can save a lot of costs for users without pollution.

Such environmentally friendly products, if designed for repeated use, will greatly improve their environmental protection. Today, Xiaobian has brought a reusable intelligent writing book, Elfinbook, a reusable notebook.  

The Elfinbook rewritable notebook is packed in ordinary hard paper. In addition to the product name "Elfinbook rewritable notebook" on the front, three pictures introduce the use effect of the product APP. There are eight functions below the front, of which the first four are the characteristics of stone paper, and the last four are the functions of the app.

Elfinbook can write a family portrait of the notebook repeatedly. In addition to the product manual, certificate and notebook, there is also a erasable pen and a VIP recharge card.

Elfinbook rewritable notebook adopts the luxurious "pull ring" design in the student days. The notebook shell is hard plastic, and the surface of stone paper is smooth, soft, and similar to the feel and flexibility of silk.

Elfinbook reusable writing notebook is equipped with a Baile erasable pen. Stationery supermarkets on the market can buy it at will. The end is a rubber head, which can be used to erase handwriting. The principle is to use friction to generate heat to clear handwriting. Single characters can be used. Large areas can still be used, which will kill you. It is better to use a hair dryer or wet paper towel. The principle is very simple, and no longer demonstrated.

Elfinbook's repeatable writing notebook uses stone paper, which makes writing extremely smooth. Common pen writing also has the same effect, not because it can be wiped.

In fact, the app function of Elfinbook rewritable notebook is relatively simple. The app can automatically recognize the contents of Elfinbook rewritable notebook, store them in the form of pictures, and cannot recognize the characters or patterns in them. Due to the lack of simple functions, it is enough to understand from the literal expression alone, and I will not make a demonstration.

To sum up, the reader probably understands that the highlight of Elfinbook's rewritable notebook is the combination of new paper, erasable pen and mobile app record keeping function, which is innovative in form and optimizes ordinary use, but has a weak sense of technology; In addition, erasable pen and stone paper can be purchased at Xbao, and the price of 89 yuan is a little high; Finally, the functions of mobile apps are very practical, but not powerful. Some functions still need "member permissions". Some free functions of apps are better than their "charging functions". It is recommended to cancel the charging. After all, it is not a high-end technology. This rewritable notebook is a bit hyped and exaggerated in actual use. In addition to buying it to scare people, I can't think of any other use. After all, the price is a little high. A lot of spray, Elfinbook can packaging environmental protection products such as "stone paper" to let the majority of consumers see that it is really painstaking. Stone paper has so many advantages that it is rarely used in the market at present, because its product adaptability and high weight lead to high use costs. This requires the innovation and optimization of the whole industry in technology. It is hoped that such environmentally friendly, economical and practical products can be popularized as soon as possible.
