Most of us used crayons in our childhood, but it is estimated that few people care why we use wax as a pen.

Strictly speaking, crayons are pens made by mixing various pigments with wax. Due to the characteristics of wax, it cannot penetrate the paper and other materials, so we use crayons to draw, which is equivalent to a layer of colored wax on the paper.

Therefore, when children are young and cannot grasp the pen well, using crayons to write and draw can significantly reduce the damage to paper and even the desktop. Moreover, the wax itself is non-toxic and relatively safe. Even if adults go to cook, children can draw their pictures with ease.

The disadvantage is that the wax cannot adhere to the smooth material, so it is impossible to paint. But it also protects a lot of furniture on the side, which is more suitable for children.

Precautions for purchasing crayons

Although wax itself is non-toxic, it is not easy to eat. In addition, the crayons are mixed with paint, which is also dangerous if the paint is toxic. So when choosing crayons, we should first pay attention to safety.

At present, the more authoritative certification mainly includes the following two types:

American AP certification

EU CE certification

These two types of certification mainly indicate that the ingredients in the product that may cause harm to children or have toxic effects are within the safe range. One of the two is that you can buy for your children with confidence. If you can achieve dual certification, it is undoubtedly more reliable, but you do not need to force dual certification.
