Deli S856 Liquid Ink Rollerball Pen

The Deli S856 features a liquid ink rollerball structure with a 0.5mm tip that dispenses ink evenly, and quick-dry ink that resists smudging. The minimalist barrel design makes it suitable for students working through practice questions, everyday note-taking, or office signatures. Priced at about 3.9 yuan per pen, it offers great value and can be purchased in multiple colors and quantities.
