• Cleaning tips
• Remove the nib and leave overnight in a mix of Fairy liquid and warm water this will break down the shellac in the ink and keep the ink flowing
• To reduce the risk of blockages on the finer nibs, 0.10, 0.13 and 0.18 keep the inside of the cap damp. The moisture and humidity will help the ink flow
