Dip Pens
If you're not familiar with dip pens they are essentially simplified versions of fountain pens, instead of ink cartridges you dip the nib in bottled ink, write & repeat.
They're great for calligraphy, drawing and testing out inks, they're also perfect to use with pigmented inks that might clog a fountain pen.
