The eraser is a substance that uses a physical principle (non-magic pen) to peel off the handwriting (not only the pencil) from the surface of the written object (excluding the correction tape and the correction fluid). It is one of the most common tools in student stationery, and there are many different erasers available in the market today.
In daily life, you must have such a small question, why did you just buy the eraser for your child, how come you buy new ones so soon?
Eraser corroded in other stationery
In addition to the usual student eraser, there are also brown erasers commonly used by artists, made of soft and rough rubber. It is designed to erase large areas of the mark without breaking the paper. However, this eraser does not erase the handwriting very efficiently and accurately. It is worth noting that the eraser used by students has a scent. This scent is a volatile oil. If the plastic and the eraser are put together for a long time, the oil (organic solvent) volatilized by the eraser can dissolve the plastic in a small amount, which causes the eraser we see to corrode. The stationery is on, which is one of the reasons why the eraser has to be replaced.
Like a single fancy eraser
You will surely find that in today's market, student erasers have a variety of shapes and aromas. Many pencils have an eraser head, but students are obviously keen to buy a separate eraser. There is no reason for it. The single eraser is clean and has a "beauty". In order to attract the attention of consumers, the plasticity of the stationery is carved into "artworks", with small flowers, small insects, small houses and so on. The more "beautiful" the more attractive, the more attractive the partners of the "Appearance Association". Collecting these fun rubbers has become their favorite, and even if they are not used up, they will make up early.
Never used a whole eraser
In addition, the eraser is easy to lose or play because it looks good and small. How can I play it? Some children will cut into small pieces and play games, or deliberately write a lot of text to wipe a shape, such games will quickly make the eraser "end to sleep." Therefore, it is normal for each eraser to be completely used up, but this promotes the replacement of the eraser.
