Yongsheng Junlai 630 Acrylic Fountain Pen Size 8 Medium Nib - Smooth

Our review of the Yongsheng Junlai 630 finds it best suited to writers who want a classic-looking, lightweight piston fountain pen with a large #8 nib and visible ink. The single biggest reason to consider this pen is its combination of a two-tone #8 iridium medium nib and a transparent fence ink tank, which together deliver largely smooth, consistent writing and the convenience of watching ink levels while filling. It is a clear option for daily note-taking, journaling, and casual calligraphy without a heavy price or heavy feel.

Key Features

• Torpedo shape and piano lacquer: The glossy piano lacquer finish and torpedo profile give the pen a refined, durable look that resists dulling during regular use.
• #8 two-tone iridium nib: The large steel medium nib provides a silky, steady line for everyday writing and basic calligraphy work.
• Transparent fence ink tank: The clear ink reservoir makes it easy to monitor ink level and reduces unexpected refills during extended writing sessions.
• Piston filling system: The screw-cap piston is simple to use - submerge the nib and twist the end cap to draw bottled ink without cartridges.
• Lightweight balance: At about 0.72 oz / 20.5 g without the cap, the pen offers comfortable all-day handling and a secure metal clip for pocket carry.
• Hand-assembled quality control: Each pen is manually assembled and inspected before shipping to help ensure a reliable out-of-box experience.

Who It's For

The Yongsheng Junlai 630 suits students, professionals, and hobbyists who want an affordable, attractive fountain pen with a large nib and visible ink that writes smoothly for most everyday tasks. Its light weight and balanced feel make it useful for long notes, journaling, and general office use.

Serious collectors or those who need guaranteed factory-perfect nib alignment and flexible gold nib behavior should consider higher-end options; some buyers report occasional nib issues out of the box, so users who cannot or prefer not to adjust a nib may prefer pens with stronger post-sale support.
