In this video, I finally put the viral Uniball Zento lineup to the test—especially the Zento Signature that’s been sold out everywhere. I walk you through Uniball’s new ink formulation (what they’re claiming is different and why it matters for everyday writing), then I introduce the Zento family so you can see where the Signature model fits in the lineup. If you’ve been wondering whether it’s genuinely a new experience or just a shiny new body with hype attached, I’ve got you. From there, I do the cozy, practical stuff: I compare ink types side-by-side and swatch Uniball One ink versus the new Zento ink so you can actually see the differences in saturation and overall look on paper. I’m paying attention to the things that matter in real planner life—how it feels, how consistent it is, and whether it’s the kind of pen you’ll reach for daily in a pocket notebook or planner system. By the end, I share my final thoughts on whether the Zento Signature is worth your money, or if you can happily skip it and stick with what you already love.
