This is a Pilot Custom 742 black fountain pen. The Custom 742 is a popular model in Pilot's Custom series, known for its "just-right size" and "authentic writing feel." It's slightly larger than the Custom 74, providing a secure and comfortable grip, but not as large as the Custom 743, making it very suitable for everyday use. It features a #10 size 14K nib, offering the precise writing performance that Pilot is known for. The nib is 14K Medium (M). With a balanced line width that's neither too thick nor too thin, it's a standard choice that can be used for a wide range of writing, from notes to letters and everyday writing. The ink flow is also stable, allowing for a smooth and stress-free writing experience. It's a line width that works well with Japanese writing. The condition is extremely good. There are no noticeable scratches, scuffs, cracks, chips, or malfunctions, and there is no engraved name. The writing and mechanism have been tested and are working without any problems. This listing is for the pen body only. Please note that the box, ink, and converter are not included.
