To use just the converter (without the needle), simply detach the syringe needle portion before use.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I fill my fountain pen using this ink filler syringe?\u003c\/h4\u003e\n\u003cp\u003eA: Dip your assembled fountain pen tip into your bottle of ink, press the spring bar down fully, then slowly release it. This creates suction that draws ink up into the converter. It's a clean, straightforward process that takes just seconds.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this tool to clean or flush my fountain pen cartridge?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The ink filler syringe is excellent for both filling and flushing fountain pen cartridges and converters. Simply use water or a pen flush solution instead of ink to clean out old residue between ink colour changes.\u003c\/p\u003e\n\u003ch4\u003eQ: Is assembly difficult?\u003c\/h4\u003e\n\u003cp\u003eA: Assembly is simple — connect the three parts (converter, white connector, and needle) at their correct ends. Wrapping the connector with a small cloth and applying a little grease helps seat everything snugly. A slightly firmer push may be needed the very first time you assemble it.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
