Multi-functional pen (choose 2 ballpoint pens + sharp diameter).
It can be used with a sharp and a ballpoint pen in one roll.
Product Features:
The product has been improved with the improvement of "rattling when you shake the pen" from the traditional sherbo, and it has improved the rigidity of the product.
The working part is made to create a "tight" rotation when switching between the core.
Uses a spring-loaded clip that is easy to clip on thick notebooks, etc.
It also has a gray eraser so that the dirt is not visible after erasing.
The head knock part is made with elastic elastomer for a moist, sharp knock.
