Nothing is isolated in human society, everything always goes together to support each other. So from the time students know they come to school, there will be bags born. Since people knew how to use pens and rulers for study and work, pens and rulers also appeared from there. Pen tube – a very familiar tool for students, but to fully understand it, we need to consider many aspects.

Compared to the history of ballpoint pens, eyeglasses or some other items, the pen holder is not mentioned much. Although there is no definite date, it can be affirmed that the pen tube was born in parallel with the time of the pen's birth. According to some historical records, in the Middle Ages, poets, historians... used a pen holder shaped like a flower vase to stick brushes. This pen tube is made of porcelain with decorative patterns on the outside, but it is only placed on letters and is very inconvenient to move. Perhaps that is why horizontal pen cases were born later.

However, at present, environmental problems are a burning problem of many countries in the world today, including Vietnam. Every year, millions of tons of waste and waste are discharged, not only negatively impacting the environment but also affecting human health. If they are reused, it will bring economic efficiency and significantly reduce the amount of waste. So, recycling old plastic to create beautiful and unique things in the family can help protect our environment.

We can find enough materials to make a pen holder such as: A piece of cardboard about 15cm long, about 20cm wide. Colored paper, scissors, glue, staplers, dried flowers,... Remember those plastic bottles? It would be the perfect material for a beautiful fountain pen. Unlike in the past, today the materials for making pen tubes are extremely diverse. It is everything around us that can be used. Although very diverse in types, but in general, the pen tube has two parts: the outer shell and the hollow core to hold the pen.

Thanks to it, students can arrange learning materials such as pens, rulers, compasses, pastels, sticky notes, etc. neatly. Not only that, the pen holder also has the function of protecting the pen and ruler safely. It will be the companion of students, students and some other professions. For us, it is not only a place to store essential items but also a place to hide memories. Therefore, each of us must cherish this object and keep it carefully.

It only takes a little time to have a small pen holder in the study corner that looks beautiful and convenient. School age with white shirt and future aspirations cannot be without such good friends. Let's create a companion for us, for our environment, for the life of humanity.
