The Faber-Castell Basic line, also known as Essentio, are fountain pens that are pretty much what their name implies. A basic, modern design that is complemented by quality craftsmanship and materials. If you are just getting into fountain pens these are a good place to start. They are stylish, great every writers and are fairly cheap which makes them excellent every day carry pens.
A standard cartridge is included in the box and converters are sold separately, although it’s worth noting that not all converters might fit into the barrel of the pen.
Apart from the standard metal barrels, the Basic also offers the barrel in a carbon design which Faber-Castell dubs “durable carbon” as well as sheathed in leather.
