The new 2019 Momento Zero Resin Pietra Marina (sea stone) is a stunning addition to the range. With its pearlescent blue and brown shades, this is a writing instrument that has to be seen to be fully appreciated. The contrast of the rhodium plated trim and clip works perfectly. Each pen is individually numbered and features a finely engraved barrel. The steel nib offers lovely feedback and being a cartridge / converter pen (supplied) you have the best of both worlds.
