## Description

Signo RT1 Ultra Micro Tip 0.28mm Rubber Grip Blue Black 3 Pens with Kanji Love Sticker Renewal An ultra-fine 0.28mm retractable gel ink ballpoint pen that can write smoothly. Very fine but smooth. By eliminating the corners of the tip and the signo ink of the new formulation, the friction resistance between the pen tip and the paper is reduced and a smooth writing taste is achieved. It is a one-motion design where the connection between the handle and shaft is inconspicuous. Borderless tip without corner at the top of the tip. To reduce the friction resistance between the pen tip and the paper, the corners at the tip of the tip have been eliminated to achieve a smooth writing experience. In addition, the stainless steel tip is excellent in toughness and the nib mechanism that prevents the direct current of the ink. Smooth new composite ink. By checking the ink composition, we have improved smoothness while maintaining the vibrancy of the ink colour and the property of being able to draw ultra-fine lines without bleeding. Uses a dark, non-bleeding water-based pigment ink. It also has excellent water resistance and fade resistance. Flowing One Motion Design A new design with no noticeable connection between handle and shaft. The simple, smooth and flowing shape is attractive. In addition, the entire toe shaft has a rubber grip that is easy to grip.
