Pilot MetropolitanThe Metropolitan is the honest starter recommendation — consistent nib, reliable converter feed, sub-$25. Fine or medium nib first.

Leuchtturm A5 (dot grid)A5 dot grid is the format most fountain pen users land on. Leuchtturm paper handles most inks without bleed-through.
Piston converterA standard converter turns a cartridge pen into a bottled-ink pen. Pilot and LAMY converters are brand-specific; verify fit before buying.
