A perfect combination of style and functionality, the impressive design of the Pilot Prera series will amaze every pen lover. Prera pens feature a transparent profile which allows the user to check the volume of the ink. These fine writers are equipped with a special capillary controlled ink delivery system that controls the ink flow and prevents bloating and smudging issues. Prera pens also include a vacuum sealing system that stops the nib from drying out inside the ink. Prera pens take cartridge/converters as an ink reservoir.
