In the process of learning, the eraser is an essential school supplies, it can help us wipe out the typo, but after you use the eraser, you will find a lot of black spots like ants, you have to wipe it off by hand. It is very troublesome. But I don't have this phenomenon when I send the eraser that I invented in the future. Its shape is a rectangular avatar, the color of the eraser can be exchanged according to your favorite, just say "what color" will automatically change. When you write it, you accidentally write it wrong, but you can't find it. The eraser will send a red alarm to remind you to wipe it off. When you erase the typo with an eraser, there will be black spots like ants. Don't worry that our magic eraser will use a small straw like a vacuum cleaner to suck the black spots and turn the black spots into air. Is such an eraser amazing? But in the future I will invent such a magical eraser!
