Among my school supplies, there is a beautiful stationery box. It was given to me by my mother because of my good results in the final exam the year before. It has been with me for more than a year.

This stationery box, 21 centimeters long and 8 centimeters wide, is dressed in a pink coat. The ** of the stationery box has a diagonal line, like a rippling microwave in the lake; Next to the slash is a kitten holding a lively and cute little white rabbit in her hand. The kitten was wearing a blue dress, with pointed ears and a bow on it, and several long whiskers stuck in its mouth, which I heard was a flexible ruler.

The most striking thing is her big eyes that are always on high alert, a small round nose, and a mouth that has disappeared nowhere. In the upper left corner of the kitten, it was written "hellokitty", and I finally understood that the kitten's name was "hellokitty". These colors and patterns make my stationery box look beautiful.

When I opened the stationery box, the design inside was very ordinary, like a large and small room, which was particularly interesting. The bottom layer of the stationery box is used to hold English flashcards and daily notifications from teachers.

On one side of the stationery box, there is a small clasp that is used to close the lid of the stationery box. When I opened my bag, the first thing I saw was my beautiful stationery box.

When I saw it, I felt like I saw an article, a math problem, a picture, and a homework. It has made a special contribution to my cultural knowledge, and I must cherish it.

My favorite school supplies – stationery boxes.

In my school bag, lying quietly lies a stationery box that has been with me for four years, which was a birthday present from my mother when I was in second grade. Although the edges and corners are a little damaged, the clear picture on the stationery box is still so cute!

On its left is a naughty rabbit wearing a left earphone, holding a microphone, singing, one hand still in his pocket, full of spirit, like a big singer, with the words "radish rabbit" written on the bottom left. On the right, on a "grassy field", two bunnies are playing football. Not far away, there is a small house with red tiles and white walls, which is probably the home of the little rabbit.

In the sky, carefree with a few small birds flying. Lo and behold, there are a few birds on the branches that are turning and listening to whose singing voice is more likely!

Now, let me introduce you to the internal members of the stationery box: my stationery box is divided into three layers: upper, middle and lower, which is very exquisite. On the first floor lay two brothers, a red and blue ballpoint pen, plus a heavy compass.

A hero fountain pen is wearing a dark red cheongsam and a small silver-white hat lying quietly in a stationery box. There's also a handy mechanical pencil. On the third floor, there is a simple folding ruler, which is dressed in a long pink dress, like a beautiful and quiet girl.

By the way, there's also a little eraser that hasn't been introduced, it's always been silent.

The stationery box is not only beautiful in appearance, but also has a beautiful internal structure, which has also made great contributions to my studies. While I was doing my homework, the blue ballpoint pen rushed out of my seat and allowed me to finish my homework with ease. When I was writing an essay, a red ballpoint pen came out and asked me to make revisions on scratch paper to make the essay more specific and vivid.

When I was doing the reflection question, the pencil that was sleeping sweetly also woke up from its sleep and jumped in front of me, as if proudly saying, "Little master, you should use me this time!""Sometimes, when I make a mistake, the silent eraser will rush over and wipe the typo clean with three strokes and five divisions.

In math class, the compass showed its skills, it stretched one leg diagonally, stood on one leg, and turned on the spot, and a circle appeared on the notebook. The quiet ruler helped me draw standard line segments, so that I could complete the assignment successfully. The pen is not a small credit, and the writing class has arrived.

It "rustled" and swung nimbly in my hand, allowing me to write quickly and well.
