Waste in stationery:

Rubber:

Many erasers are cute, and everyone loves them until they are taken apart. But once it is taken apart, it will be damaged, such as poking holes in it, etc.

Notebook.

Notebooks vary in number of pages and are getting more and more beautiful. Gradually, the number of pages in the notebook will become less and less, and the notebook will become thinner and thinner.

Children have strong hands-on ability and like various origami games. We will find that notebooks usually turn into various paper cranes, small frogs, paper airplanes, etc.

How to avoid waste?

Don't buy too much stationery and let it sit idle at home. It can guide children to use stationery to create, which can not only increase knowledge, but also satisfy the psychology of hands-on creation.

Do not buy such stationery!

The abnormal whiteness of the workbook may be caused by the addition of a large amount of fluorescent self-enhancer during the production process. Long-term use of such exercise books will affect students' vision; at the same time, after the optical brightener is absorbed by the human body, it will increase the burden on the liver.

Excessive exposure to optical brighteners may be a potential carcinogen.

Correction fluid contains paraxylene, which can cause chronic damage to the liver, kidneys, etc. with long-term use.

The concentration of benzene in inferior correction fluids mostly exceeds the standard. Mild can cause headache and nausea if inhaled for a long time.

Severe cases can lead to leukemia.

Stationery has become an indispensable tool in daily life.
