How to check the authenticity of 2b pencils is as follows:

1. Look at the logo. Put several pencils together and compare them to see if the "2B" logo positions on three sides of the pen barrel are exactly the same. If they are uneven, it is a fake.

2. Look at the texture. The genuine wood is moderately soft and hard, with the same texture on the outside and inside, and is dark red in color; the fake is only painted red on the top, and the wood is white or light yellow after being peeled; when sharpening a pencil, the fake wood is too hard and easy to split.

3. Look at the packaging. The authentic handwriting is finely printed, while the fake is blurry, the printing distance is uneven, the paint is black, and the surface is not smooth.

4. Look at the curling. The genuine product is rolled smoothly, while the fake product is difficult to roll, and the wood texture is rough and easy to split.
