Professional writing instrument

The Pilot Acroball Pro 31910 is a retractable ballpoint pen designed for everyday office and personal use. It delivers a 1.0mm line width in black ink and features a silver barrel with metal accents for a refined appearance. The pen suits anyone who wants a reliable, refillable tool for extended writing sessions.

Hybrid ink flow and comfortable grip

The Acroball® hybrid ink combines the smoothness of a gel with the quick-drying properties of a traditional ballpoint, reducing smudges during normal use. A tungsten carbide nib resists deformation and wear, while the textured ergonomic grip helps maintain control without excessive pressure.

Refillable design extends service life

Because the pen is refillable, users can replace the ink cartridge instead of discarding the whole unit, lowering long-term cost and waste. The retractable mechanism protects the tip when not in use, and the durable metal accents withstand daily handling in a busy workspace.

Questions about this item

How do I install the refill in the Pilot Acroball Pro 31910?

Unscrew the barrel, remove the old refill, insert the new Pilot Acroball refill, and reassemble; the step people miss is ensuring the refill seats fully before tightening.

What maintenance or replacement will the Pilot Acroball Pro 31910 need later?

Replace the ink refill when the 1.0mm tungsten carbide nib runs dry; the nib itself resists deformation and wear.

What limit appears first during sustained writing with the Pilot Acroball Pro 31910?

Ink depletion is the first limit; the hybrid ink dries quickly like a ballpoint while writing smoothly like gel.
