“Science” Rollerball

Description ACME writing instruments are typically distinguished by the works of modern and contemporary designers. The “Science” rollerball speaks to the talents of Leonardo Da Vinci. Its design is centuries old, but it still appeals to a modern sensibility. This rollerball is fitted with an ACME black ink refill. It can be converted into a fountain pen with an ACME fountain pen conversion unit, which is sold separately.
