1. A notebook that is too white will hurt your eyes

Whiteness refers to the overall reflection ability of paper after being illuminated. The paper with high whiteness can reflect almost all the color light, and it looks bright and dazzling. However, from the perspective of eye protection, eyes staring at the paper with high whiteness will affect vision over time. All kinds of accessible parts on the operation book form sharp edges or burrs due to poor processing quality or abnormal use, which are called sharp edges and sharp tips. The exercise book is mainly used by underage students. During the use of the exercise book, sharp burrs may cause students to be stabbed and cut.

2. The fragrant stationery should be carefully selected

Avoid buying "three noes" products. In addition, don't pay too much attention to the "color, fragrance" of stationery when buying. You should open it and smell it. Inferior products have obvious pungent smell, or there is an abnormal strong fragrance caused by adding inferior essence. It's best not to choose.
