These pens are also suitable for color-coding emotions and thoughts, making 'the moment of writing more comfortable.' 'uniball ZENTO 3-Color Ballpoint Pen' The special website also introduces the new 'uniball ZENTO 3-Color Ballpoint Pen'. https://www.mpuni.co.jp/special/uniballzento/index.html The 'uniball ZENTO' series is a next-generation water-based ballpoint pen that took six years to develop, pursuing the essence of 'writing' to achieve a new sensation of smooth, soft writing. In addition to its new writing feel, the series debuted with multiple single-color models, allowing users to choose a pen that suits their preference. This time, the company is launching the series' first 3-color ballpoint pens in three models simultaneously. While inheriting the simple, high-quality designs of the existing single-color 'Signature Model,' 'Flow Model,' and 'Standard Model,' these new pens incorporate a 3-color refill in a slimmed-down body. They are ideal for the unique 3-color ballpoint pen use case of color-coding emotions and thoughts. [Concepts Inherited by Each Model] The pens inherit the 'smooth writing feel' and the iconic design of each model that have been well-received in the single-color 'uniball ZENTO' models. While single-color and multi-color ballpoint pens often have different designs, the 'uniball ZENTO 3-Color Ballpoint Pen' keeps the barrel slim despite housing a 3-color refill, preserving the design concept and functionality that supports a stress-free writing experience from the single-color models. It is designed to help customers better appreciate the value of 'making the moment of writing more comfortable' as part of the 'uniball ZENTO' series. [Product Features of Each Model] uniball ZENTO Signature Model Rotary Retractable 3-Color Ballpoint Pen ■ Dedicated Rotary Retraction Mechanism and Cap Design Despite being a multi-color ballpoint pen, it adopts a cap-type mechanism. The satisfying attachment and detachment feel of the magnetic cap, and the design where inserting the cap onto the rear end of the barrel completes the form for writing, inherit the identity of the single-color model and maximize the soft writing feel. It also employs a rotary retraction mechanism that allows the pen tip to be extended while the cap is attached to the rear end of the barrel. The rotating part features a knurled finish for a non-slip, easy-to-operate design. Attention has been paid to the click feel when extending and retracting the pen tip, creating a sensation of 'switching on the writing mode' along with the satisfying 'click' of attaching the cap to the rear end. uniball ZENTO Flow Model 3-Color Ballpoint Pen ■ Metal Parts that Subtly Express Attention to Detail It adopts the aluminum grip characteristic of the Flow Model, achieving a smooth writing feel with an appropriate sense of weight and stable writing. The grip features two types of finishing—blasted and hairline—creating a design that allows users to enjoy the difference in texture. Furthermore, color-coordinated metal parts subtly gleam, adding a touch of elegance. uniball ZENTO Standard Model 3-Color Ballpoint Pen ■ Minimalist Design Expressing the Versatile and Easy-to-Use Nature of a Standard Model Pursuing ease of use as a basic model, it inherits elements from the single-color model, such as a rubber grip covering the tip, a simple barrel design, and a color lineup. When knocked, the knock bar and barrel integrate, giving a seamless impression and allowing users to 'enjoy a comfortable moment of writing.'
