A pencil can be sold for 20 yuan. Is there anything special about this kind of net red pencil? It's the first time to know that the pencil didn't contain lead. In fact, for parents, it's best to buy the most common pencil for their children. Don't cultivate the mentality of comparison between children!
'20 yuan a pencil, do you want to buy it for your son? I'm hesitant!' Ms. Wang's child will go to the first grade in September. She is shopping online for school stationery these two days. However, a pencil has been lying in her 'shopping cart' for several days and has not placed an order yet. Ms. Wang said that the pen is full of holes, commonly known as "hole pen". It is said that "hole pen" can not only correct the gesture of holding the pen, but also has a big selling point: lead-free poison.
However, the reporter confirmed that all the pencils on the market now do not contain lead, "unleaded poison" is a full gimmick.
'net red' pencils are very expensive
As the school begins, many new life mothers will start a Dongdong pen when they prepare stationery for their children recently. There are many brands that are sold by manufacturers, some of which are foreign brands. "It's said that children can correct the gesture of holding the pen when they use this Dongdong pen," Ms. Wang told reporters that many Dongdong pen businesses have made the slogan of "lead-free, safer".
Ms. Wang is also very excited about this Dongdong pen. After surfing the Internet, it turns out that Dongdong pen has become the online Red stationery for the start of school. Many businesses sell it, and some of them sell thousands of pens a month. But when she looked at the price, she was shocked. A pen cost more than ten yuan, and the most was more than 20 yuan. 'it's impossible to buy only one pen. It costs 200 yuan to buy a dozen! A dozen ordinary pencils cost only a few yuan! The difference is too big.'
Reporters input "dongdongdong pen" on an e-commerce platform to search for products, and immediately jumped out of a number of Dongdong pens, many of which emphasized that this pencil can correct the gesture of holding the pen, and many of them have printed the words "lead-free poison", with the price usually around 20 yuan.
And offline stationery stores also have the figure of "dongdongbi". Reporters in a stationery store in Hongkou District saw that the Dongdong pen was placed on the most eye-catching sales counter. According to the owner, it's about to start school, and Dongdong pen is very popular.
In this stationery shop, the price of Dongdong pen ranges from 18 to 22 yuan. Why is this pencil so expensive? The owner said that the main function of the Dongdong pen is to help children correct their posture when they write. When they hold the pen, their fingers are naturally embedded in the hole, so that they can form the correct gesture. The owner also stressed that the biggest advantage of dongdongbi is lead-free. According to the owner, considering that some children usually like to bite the pen, the end of the hole pen is made of 'edible material'.
'lead free' is actually a gimmick
In the interview, the reporter learned that the pencils on the market, in fact, do not contain lead, take 'lead-free poison' as the selling point, in fact, it is a gimmick.
"Pencil is not made of lead at all." Cai Caihong, who graduated from chemistry department of East China Normal University, now works as a chemistry teacher in Zhongxin international school. She explained to the reporter that the main component of pencil is actually graphite, which has color and lubrication, and can stick to paper. Graphite is an allotrope of carbon element at the same time, which is completely non-toxic. 'graphite and lead are totally different substances. '
The pencil manufacturer also confirmed Mr. Cai's statement. Peng, director of the general office of China first pencil Co., Ltd., the manufacturer of 'China pencil', told reporters: 'because of the name of the pencil itself, some people who are not sure about it mistakenly think that there is lead in the pencil. In fact, pencil lead is made of graphite and clay, completely free of lead '.
So, why is pencil called "pencil"? Zhu, a chemistry teacher at another high school in the city, said that graphite can leave traces on paper like lead, which is much darker than lead. Therefore, people call graphite "black lead", and the name of "pencil" may be called like this.
