Review: Worth the hype - Very smooth, nice and inky black pigment, minor bleed through on poor quality paper. The only complaint I have is that the grip area is a bit too wide for my writing style and causes cramps. But for people who prefer a thicker grip, this works really well. Since it uses the same ink refills as the significantly more expensive Signature version, it is too good to pass up. I don't think I will be switching off of this pen any time soon Review: Smooth black - Smooth. Really. Original uni ball. ## Features - SMOOTH WRITING EXPERIENCE: Water-based ink technology delivers exceptional smoothness and precision with reduced friction for effortless writing - QUICK-DRYING FORMULA: Ink dries in just 0.2 seconds on most papers, preventing smudging and ensuring clean, professional results - LONG-LASTING PERFORMANCE: Each pen can write up to 700 metres, providing extended use and excellent value in a pack of 1 - PRECISE FINE POINT: 0.7mm tip creates clear, defined lines perfect for everyday writing tasks and detailed note-taking - MINDFUL DESIGN: Engineered to enhance writing comfort and control, promoting a focused and relaxed writing experience ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0F2MSHCHC | | Additional Features | Eco Friendly, Ergonomic, Pocket Clip, Quick Drying, Smudge Free | | Age Range Description | 3 Years And Up | | Age range (description) | 3 Years And Up | | Best Sellers Rank | #1,145 in Office Products ( See Top 100 in Office Products ) #11 in Liquid Ink Rollerball Pens | | Brand | POSCA | | Brand Name | POSCA | | Color | Black | | Colour | Black | | Customer Reviews | 4.6 out of 5 stars 18 Reviews | | Drill Point | Fine | | Grip Type | Rubber | | Included Components | Pen | | Ink Base | Water | | Ink Color | Black | | Ink colour | Black | | Item Diameter | 0.7 Millimeters | | Item Dimensions | 10 x 10 x 5 centimeters | | Item Weight | 15 Grams | | Line Size | 0.7mm | | Manufacturer | uni-ball | | Material | Durable open wire clip, Long Rubber Grip, Recycled Plastic Material | | Material Type | Durable open wire clip, Long Rubber Grip, Recycled Plastic Material | | Model Name | Zento | | Model Number | MI-UBNZS-07-01BK | | Style | Japanese | | Theme | Mindfulness Enthusiasts, Zento | | Unit Count | 1 Count | | Writing Instrument Form | Roller Ball Pen | | Writing instrument form | Roller Ball Pen | ## Product Details - **Age range (description):** 3 Years And Up - **Brand:** POSCA - **Colour:** Black - **Ink colour:** Black - **Writing instrument form:** Roller Ball Pen ## Images ![Zento Rollerball Pen, Fine 0.7mm, Water-Based Black Ink, Ultra-Smooth with Reduced Friction, (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/415BE+7o0xL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth the hype *by M***Y on 31 May 2026* Very smooth, nice and inky black pigment, minor bleed through on poor quality paper.
