Choose M if you write larger, prefer a wetter line, or want to showcase ink shading and sheen. When in doubt, F is the most versatile starting point.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eQ: What inks are compatible with this pen?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eA: Compatible with all standard bottled fountain pen inks.
