Anterique BP1 Ballpoint Pen 0.5mm Refill

Refill for the Anterique BP1 and Anterique BP2 ballpoint pens. 

Ballpoint pens in the past used "sticky" ink, but Anterique's oil-based ballpoint pens use "ultra-low-viscosity ink" (Mach ball ink). Ultra-low-viscosity is ink that is "smooth" and easy-flowing.  

Why it's special:

• High-precision tip 0.5mm tip
• Ultra smooth dark black ink
• Thick and durable plastic body

Specifications: 

• Tip size: 0.5mm
• Made in Japan by Anterique Stationers
