Description The TWSBI Diamond 580ALR fountain pen in Punch Pink features a clear acrylic body, cap and turning knob, bright pink trim, a brushed aluminum grip section, as well as a piston ink-filling system, smooth-writing steel nib and a screw-on cap. The aluminum in the new 580ALR has been updated with circular engravings in the grip and cap area, and a subtle matte finish. The TWSBI Diamond 580AL piston ink-filling system uses only bottled ink and the clear body allows the user to view the level of ink remaining in the pen at all times. The pen cap has an inner cap liner that maintains a thorough seal when the pen is not in use. The traditional mechanism of the fountain pen, combined with a modern industrial design, embodies both the past and the present. 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.
