Uni-ball Fine Deluxe UB-177 Blue Ink Pen

Core Features & Benefits
Uni-Flow System: An internal reservoir mechanism that ensures a smooth, continuous flow of ink with consistent thickness down to the very last drop.
Uni Super Ink™: A specialized pigment-based ink that bonds to paper fibers, making it waterproof, fade-resistant, and tamper-evident—ideal for writing checks or signing permanent records.
Writing Performance: Features a stainless steel tip with a 0.7 mm tungsten carbide ball. While the ball is 0.7 mm, it typically produces a precise 0.3 mm to 0.5 mm line width.
Professional Design: The barrel is made of durable plastic (PP) with a sleek gunmetal or matte finish, complemented by a sturdy metallic pocket clip.
