Calligraphy pen can be preserved after use by

To preserve a calligraphy pen after use, you should rinse it in cold water. This is because calligraphy pens are typically made of materials like metal, plastic, or wood, and these materials can be damaged by hot water, oil, or grease. Rinsing the pen in cold water will remove any ink residue and prevent it from drying inside the pen, which can clog the nib and make it difficult to use in the future. Once the pen is rinsed, gently pat it dry with a clean cloth or paper towel, and store it in a cool, dry place. It's also a good idea to store the pen in a protective case or pouch to prevent any damage or scratches, and to ensure that it stays clean and free from dust or debris. With proper care and storage, your calligraphy pen can last for many years and continue to produce beautiful writing.
