Review: This pen writes smoother than a jazz saxophone in a bubble bath - I don't usually get emotional about office supplies, but these Uni-ball One pens? They changed me. The ink glides like it's on a mission from the handwriting gods. No scratchiness, no hesitation, just pure, silky lines that make my grocery lists look like calligraphy written by a monk with perfect posture. The 0.5 mm tip is sharp enough to slice through my existential dread but gentle enough for even the most fragile Post-it Note. It dries fast too, which is perfect for lefties, impatient people, or anyone who’s ever accidentally dragged their hand across freshly written text and ruined both the paper and their will to live. The clip is strong, the click is satisfying, and the pen feels expensive enough to trick people into thinking I have my life together. I bought the 12-pack so I could lose 11 of them slowly over the next year like a true adult. If you want a pen that writes like a dream and makes you feel 10% more competent, get this. Then write a thank-you note to yourself in perfect, smudge-free ink.
Review: One of the best pens you can get regardless of price! - I absolutely love this pen. Extremely comfortable to hold. Looks fantastic and a joy to write with. The secret is their ink. I don't know what their formula is but it's going to be one of the best writing pens you will ever own. I have expensive pens that does not write as well as this. For the price, you can't beat this!
