### ⭐⭐⭐⭐⭐ The best of its kind

These refills have been class-leading products since their launch. The ink is non-drying and the writing is super-smooth. Even for heavy writers, the duration of each refill is superlative! I've been using Mitsubishi dot pens along with these refills for over three decades and it astonishes me that no other product surpassed these! Zebra is the only other brand that can give Mitsubishi pens and refills a fair fight. I regard these refills and Mitsubishi dot pens as best and urge everyone to use them so that the legacy lives forever.
