Look at the texture: the real thing has the same texture, the fake thing is of poor quality, the refill is very easy to break, and the color is not as deep as the real thing when used.

Look at the package: the genuine handwriting is finely printed, the fake is blurred, the printing distance is uneven, the color is dark and the surface is not smooth.

2B Precautions for mechanical pencil

When using 2b mechanical pencil to paint the answer sheet, the strength must be moderate, otherwise it is easy to break the refill, or cut the answer sheet, and you can't use insufficient force, otherwise it will make the color lighter, which will lead to the failure of normal scanning and affect the test results. Also, be sure to contact how to refill in advance, otherwise you will be too flustered during the exam and will delay a lot of time. ?

You can use it according to your personal habits during the exam. As long as you put the answer sheet on the answer sheet, you can paint the card once every time you finish a certain number of multiple-choice questions, or you can paint all the multiple-choice questions at once, depending on the test habits and time.
