When do you need refills?
If you write regularly with a ballpoint pen, it's handy to have refills to hand so you don't have to buy a new writing instrument every time. These PILOT ink cartridges are designed for anyone who wants to keep using the same pen and doesn't want to waste anything unnecessarily.

Which pens is this cartridge suitable for?
This refill cartridge (reference RFN-GG-L) fits specifically in the PILOT ballpoint pens BP-S, BPS-GP, BPE-GP and SUPERGRIP G. So before purchasing, check that your pen is one of these models — compatibility is the decisive factor here. If you use a different PILOT pen, this cartridge may not be the right choice.

What does a writing width of 0.29 mm mean in practice?
With a writing width of 0.29 mm, you put a fine, crisp line on paper. That makes this cartridge suitable if you write a lot of small text or want to work precisely, for example when filling in forms or keeping notes. The ink is also document-proof, meaning the written text is durable and suitable for official or archival documents.

Practical: packaging and stock
The cartridges are supplied per box of 12 pieces, which is good value if you use the pen in question daily or have several pens of the same type in circulation. Store unused cartridges in a dry place at room temperature so the ink keeps its writing properties. That way you always have a working refill ready without having to reorder each time.
