@The Mechanic just ask for a pilot cartridge. Nowadays V5 and V7 have the same cartridge since V5 refills are now available.
@calvinhobbes When you are a lefty, your hand is usually on the place where you actually write. In righty, your hand is away from the paper. A hack for that is to keep the notebook slightly tilted so my hands are a bit away from the paper.
2019, V5 Cartridge, after 4 refills, roller lost hold of its nib. Haven't used it post this.
