TWSBI believes that it is important to allow the user to disassemble and reassemble the pen, in order to completely experience the traditional aspects of owning and using a fountain pen. The TWSBI pen packaging includes a wrench and silicone grease. ** Please note that these accessories are not intended to be used immediately, as they are better used for long-term care and maintenance. In addition, please use extra care if you choose to disassemble the pen, as breakage or cracking could occur if done incorrectly.
