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 Royal Blue is a classic medium blue and one of the safest inks out there.

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