Kaweco : Perkeo Fountain Pen :

Originally released as a dip pen in the early 1900’s, Kaweco has re-vamped their Perkeo as a convenient cartridge/converter fountain pen, perfect for beginners. Featuring a multifaceted resin body, an ergonomic triangular grip to keep your fingers in position for consistent flow, and a hidden transparent section so you can check on your ink levels without disassembling your pen. Available in fine or medium stainless steel nib, and in off-beat colour combos, so it’s also stylish as all get out. Comes pre-installed with blue ink.
