This TWSBI Precision fountain pen has an aluminum body and grip with stainless steel trim. It is equipped with a stainless steel nib. Like all TWSBIs, it comes with a benchmark piston ink-filling mechanism and has all detachable parts.

It uses the same nib as the TWSBI Diamond 580; however the 580 nib unit itself is not compatible in the Precision. Only the nib is swappable.

TWSBI's belief is that it is important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen. These pens also come packaged with a wrench and silicone grease. Neither of these accessories are intended to be used immediately, as they are for long-term care and maintenance. Additionally, please use extra care if you choose to disassemble the nib and feed, as the feed is very fragile.
