Kaweco Perkeo Rollerball - Jungle Green planner Available in:By Kaweco. The Kaweco Perkeo range is a super popular range of fountain pens that now also come as rollerballs! It's aesthetically similar to the classic Sport models with the octagonal shape, but with a longer barrel. It's lightweight and a cheaper price point, which make it an excellent 'entry level' option. This rollerball comes with a 0. 7mm black EURO rollerball refill, and you can buy additional refills here (also in 0. 4mm).
