The IC product line includes four types of dipping pen nibs. Each pen nib is unique and will give you different results. Use them to find out their strengths and weaknesses. Before you use your new set of nibs, use a tissue to wipe off the coating of oil gently before dipping it in ink! 

If you start having trouble drawing smooth straight lines with your dipping pen and the tip is separated or bent, it's time to discard your old nib and replace it with a new one.

There are many factors to consider when you get scratchy lines. One of them could be a faulty nib, but the other could be a clogged nib. Use a cloth a clean your nib often to avoid dried ink on the tip.

The other reason for scratchy lines could be your ink. If you leave the cap open for a long time the water will evaporate and make the ink thicker, clogging the nib. Take a dropper and add water one drop at a time until your ink is rehydrated.
