"20 dollars a pencil, do you want to buy it for your son, so hesitate!" Ms. Wang’s child will be in the first grade in September. She is online shopping to prepare for school stationery these two days, but a pencil lies on her. In the "shopping cart" for several days, there was no time to place an order. Ms. Wang said that because this pen is full of holes, commonly known as "hole pen", I heard that "hole pen" can not only correct the posture of the pen, but also has a big selling point: lead-free poison.

However, many reporters have confirmed that the pencils on the market are free of lead, and “lead-free poison” is a full-fledged gimmick.

"Net Red" pencils are sold especially expensive

As the school is approaching, many new-born mothers will start a hole pen when they prepare stationery for their children. Many brands have sold them, and some are still foreign brands. "It is said that the child can use this hole pen to correct the posture of the pen." Ms. Wang told the reporter that many merchants of the hole pen have slogan "Lead-free, safer".

For this hole pen, Ms. Wang is also very excited. When I look at the Internet, I really see that the “hole pen” has become a red stationery for the school. Many merchants have sold it, and some sales show thousands of dollars a month. But when she looked at the price, she was left in her heart. A pen cost more than a dozen yuan, and the most was more than 20 pieces. "It is impossible to buy only one. If you buy one, you will need 200 pieces! Ordinary pencil one. It’s only a few dollars! The difference is too big!”

The reporter entered the “hole pen” search product on an e-commerce platform, and immediately jumped out of a variety of hole pens. Many of them emphasized that this pencil can correct the posture of the pen, and many of them have printed the words “Lead-free poison”. The price is usually around 20 yuan.

In the stationery store under the line, there is also a "hole pen" figure. The reporter saw in a stationery store in Hongkou District that the hole pen was placed on the most eye-catching sales counter. According to the owner, the school started quickly and the hole was very popular.

In this stationery store, the price of the hole pen ranges from 18 to 22 yuan. Why is this pencil sold so expensive? The owner said that the main function of the hole pen is to help the child correct their posture when writing, and when the pen is held, the fingers are naturally embedded in the hole, so that they can develop the correct Hold the pen posture. The owner also stressed that the biggest benefit of the hole pen is lead-free poison. According to the owner, considering the habits of some children who like to bite the pen, the end of the hole pen uses an "edible material."

"Lead-free poison" is actually a gimmick

In the interview, the reporter learned that the pencils on the market are actually free of lead. Taking "lead-free poison" as a selling point is actually a gimmick.

"The pencil is actually not made of lead at all." Cai Cai, a graduate of the Chemistry Department of East China Normal University, is currently working as a chemistry teacher at SMIC. She explained to reporters that the main component of pencil is graphite, and graphite has color. It is lubricated and can be glued to 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 the statement of Teacher Cai. Director Peng of the China Pencil Co., Ltd., the manufacturer of "China Pencil", told reporters: "Because of the name of the pencil itself, some people who are unclear mistakenly think that there is lead in the pencil. In fact, the pencil lead is made of graphite and Made of clay, completely free of lead."

So, why is the pencil called "pencil"? Teacher Zhu, who teaches another high school in the city, said that graphite can leave traces on paper like lead. This trace is much darker than the trace of lead. Therefore, People call graphite "black lead", and the name "pencil" may be called like this.

It is not necessary to use a hole pen to correct posture

Then, buy a hole pen for corrective grip posture, is there any need to buy it?

Sun Yiqing, a small math teacher at Gao'an Road in Shanghai, said that the hole pen may have some effect on the child's pen posture, but parents don't have to spend a lot of money to buy it. "A general pencil can be used."

Teacher Sun feels that for children, the key is not to use any pen, but the child does not know the strength of using the pen, which will lead to inappropriate posture. "If you want to train your child's pen posture, you can first let the child graffiti on the big paper with colored pencils, then slowly make the paper smaller, let the child practice slowly, and gradually let the child master the pen's measurement."

Mr. Ding, the fourth-grade parent of her daughter, also said that there is no need to buy high-priced pencils. "Ordinary pencils can also develop good pen-holding habits. Buying stationery, simple, simple, best. Too expensive stationery, easy Form the child's comparison psychology."
