The Saturn pen has a larger center band than a Slimline pen and is therefore slightly larger and heavier than a Slimline while maintaining the classic style. The pen is approximately 5" long and 3/8" diameter (actual dimensions vary due to handcrafting process) and comes with a Cross black ink cartridge. The pictured pen (#694) is the pen you will receive and is shipped in a black felt pouch usually within 24 Hours.
