"Net Red" pencils are particularly expensive
As the school year is approaching, many new mothers and young children will start a hole pen when they are preparing stationery for their children. There are a lot of brand manufacturers who are selling, and some are foreign brands. “It is said that children can use this hole pen to correct their postures.†Ms. Wang told reporters that many of the merchants in the hole pens have played the slogan “no lead poisoning and more safetyâ€.
For this hole pen, Ms. Wang is also very exciting, on the Internet to see, and sure enough, "hole pen" has become a red net school stationery, many businesses have to sell, and some sales show thousands of months. But when she looked at the price, she put it under her mind. A pen would cost more than 20 yuan for a dozen dollars. "It wouldn't be possible to buy only one. To buy a dozen, it would be 200! Ordinary pencils. It's only a few dollars! The difference is too great!""
The reporter entered a hole-hole pen search product on an e-commerce platform and immediately jumped out of a variety of hole pens. Many of them stressed that this pencil could correct the posture of holding pens, and many of them played the words “Lead-free poisonâ€. , The price is usually around 20 yuan.
The stationery shop under the line also has a “hole pen†figure. The reporter saw in a stationery shop in Hongkou District that the hole pen was placed on top of the most prominent sales counter. According to the owner, the school opened quickly, and the hole was very good.
In this stationery shop, the price of Dongdong pens ranges from 18 to 22 yuan. Why is this pencil so expensive? The owner said that the main function of the hole pen is to help children correct their posture when writing, and when holding the pen, fingers naturally embedded in the hole, allowing them to develop the correct grip position. The owner also emphasized that the biggest advantage of the hole pen is lead-free poison. According to the shop owner, taking into account the habit of some children who like to write pens at ordinary times, the end of the hole pen uses an “edible materialâ€.
"Lead-free poison" is actually a gimmick
In the interview, the reporter learned that the pencils on the market are actually lead-free, and taking the “lead-free poison†as a selling point is actually a gimmick.
"The pencil is actually not made of lead," said Cai Caihong, a graduate of East China Normal University's Department of Chemistry. Currently working as a chemistry teacher at SMIC, she explains to the reporter that the main ingredient of the pencil is graphite, and graphite is colored. And it is lubricated and can stick on paper. Graphite is also an allotrope of carbon and is completely non-toxic. "Graphite and lead are completely different substances."
The pencil manufacturer also confirmed Tsai's statement. Director Peng of the General Office of China's No. 1 Pencil Co., Ltd., the manufacturer of “Chinese Pencilâ€, told reporters: “Because of the name of the pencil itself, some people who are not aware of it mistakenly believe that there is lead in the pencil. In fact, the pencil core is made of graphite and Made of clay, it is completely lead-free."
Why is the pencil called "pencil"? Professor Zhu, a chemistry teacher who teaches at another high school in the city, said that graphite can leave traces on paper like lead. This trace is much darker than the lead. Therefore, people call graphite “black leadâ€. The name "pencil" may also be called in this way.
Corrective posture is not necessary with a hole pen
So, buying a hole pen to use as a corrective pen posture, in the end there is no need to buy it?
Sun Yiqing, a small mathematics teacher at Gao'an Road in Shanghai, said that the hole pen may have some effects in the short-term, but parents do not need to spend a lot of money to buy it. “General pencils are enough.â€
Mr. Sun believes that the key to children is not what pen to use, but that children do not know how to use pens, which can lead to improper posture. "If you want to train your child to hold a pen, you can first let the child use a colored pencil to graffiti on large paper, and then slowly make the paper smaller, let the child practice slowly, and gradually let the children master the measure of using a pen."
Mr. Ding, the daughter of her fourth-grade elementary school, also said that there is no need to buy expensive pencils. “Ordinary pencils can also develop good pen-holding habits. It is best to buy stationery, simple and simple. Too expensive stationery is easy. Forming children's psychological comparison."
