Future pen

"Hey, this pen is always broken!" I started to complain again, stunned and continued to write, "What should I do? My correction stickers, transparent plastic?" I finally found the correction sticker, this pen There is no ink, it is a bad pen! I think: Can you design a more advanced and practical pen?

I designed a pen 13 cm long, wearing a green coat and a flower on the top. It is made of "unbreakable glass" material. Even if you are thrown to the ground and step on it with your feet, it won't break. Below, I will tell you about its features!

As long as the flowers on the tip of the pen meet the sun, its ink will grow to one-third of the hour. As soon as you write a typo, just align the flower on the head with the word, and the flower will suck it in and rise into the ink. What if you forgot to bring a triangle ruler, ruler, protractor, compass when you took a math class? Don't worry about pressing the math tools on the pen. The whole set of mathematics tools will come out of the flowers on the head and grow bigger. If you think the light is a bit dark, you click Light and he will light up!

My super pen is not bad, right? By 2045, I will definitely invent the super pen I want!
