The Kaweco Supra is similar to the Liliput but is bigger in size. However, it is still pocketable and convenient to carry around! It's customizable, as it allows the pen to be adjusted to the individual. The middle piece is an extender that allows it to be either a full size or pocket-size pen. The pen is made out of steel and each one is hand-torched, creating a unique design and color ranging from blue to purple to brown. It also features a larger #6 stainless steel nib, a screw-on cap for extra security, and an ink cartridge to get you started writing. It accepts short standard international cartridges and standard international converters. Converters are sold separately.
