How to write the composition of beloved dinosaur pen?

I have a beloved pen, which my mother gave me on my birthday. It stayed with me for a year.

It has no gorgeous appearance and is unpretentious. It can write as long as it puts on black clothes and opens the pen cover. Until now, its writing is still clear, because it can be used many times.

I seldom use it. Every time I see it, I have to touch its black body.

It is made of iron, and it feels a little cold in winter. It's a little heavy to pick up. It glows in the sun and reflects the sun. It's beautiful.

I used to paint with it. I use it to draw bamboo, telling myself to be a man with solar terms; I use it to draw grass, in order to let myself learn the tenacious spirit of grass; I use it to draw a tree, in order to make myself contribute silently like a tree; I use it to draw ... Although it is not as good as watercolor pen, I still like to draw with this unpretentious brush, because from it, I have tasted the charm of ancient China culture.

I also like it to practice calligraphy, because it contributes as much ink as it has in its stomach and is never stingy. The handwriting is so beautiful that it is often praised by my mother.

My pen, your unpretentious and consistent quality is exactly what we should learn.
