• Considering the difference in the frequency of use of black, red, and blue, this product focuses on improving the usability of the most commonly used black ink
• For the first time in a multi-color ballpoint pen, only the black part adopts a new rear end knock mechanism, allowing you to intuitively knock black without hesitation
• The red and blue inks are the same slide knock as before, but with a new mechanism, it is possible to feed and release the color regardless of which ink color has been drawn
• The most commonly used black ink is equipped with a “long-lasting refill that increases the amount of ink by about 70% compared to regular products by making the refill tube thinner
• By reviewing the shaft design, the durability against shaft cracking has been improved, and by embedding metal parts in the resin clip, the durability against clip breakage has been improved, so the shaft itself can be used for a long time. It is designed to be environmentally friendly
