4001 is the core ink range from this lauded German manufacturer and was first introduced in 1898. It is one of the most reliable and well-behaved inks available and is our pick at Bookbinders Design for a no-nonsense ink that is safe in pens new and old.

Pelikan 4001 Dark Green is a classic green colour that sits somewhere between sea green and emerald green.

Available in a six pack of Standard International Short cartridges, 4001 is the definition of bang-for-your-buck.
