This is a black pencil holder made from black to white color gradient design. On the one hand, in the process of being consumed, the black feeling gradually fades on the pen, as if the "ink of life" of the pencil is gradually receding, showing a beautiful disappearance. The disappearance is very natural, and because the process is poetic, it prompts people to make associations of what the pencil is used for, which is more of a good expectation?that the consumption of good things will turn into the same good things. The other hand, in the function of use, the dark part is always at the writing end. When people need to use the pencil as a temporary indicator stick to indicate the contents on the paper to others, they can quickly focus on the dark side of the pen and see the indicated content.
