The Writech Space Up 0.5mm Gel Pen Refill Set is engineered to maximize the lifespan of your favorite Writech retractable gel pens. Designed specifically for high-frequency writers, students, and creative journaling enthusiasts, this 5-piece replacement set delivers premium, skip-free performance that mirrors a brand-new pen.

• Advanced Twin-Ball Nib Design: Features a specialized twin-ball tip mechanism that drastically reduces writing resistance. This unique architecture optimizes ink flow to guarantee an ultra-smooth, fluid stroke without skipping or leaking.
• Rapid Dry Ink (Smudge-Free): Packed with premium, quick-drying black ink that sets instantly on the page. This prevents smearing and smudging, ensuring a highly polished, clean look that is exceptionally friendly for left-handed writers.
• Secure, Leak-Proof Engineering: Built with a reliable wax-sealed tip (to be removed before first use) and an airtight rear ink stopper. The meticulous internal sealing ensures optimal pressure, stopping ink backflow or accidental leaks in their tracks.
• Eco-Friendly & Economical: Instead of disposing of the entire pen body, swapping in a fresh refill minimizes plastic waste while maintaining your curated, aesthetic stationery collection.
