These Pilot V7 Rollerball Pens have unique Hi-Tecpoint nibs which deliver a precise line of pure liquid ink. The pens give you a bright, dense colour and the ink flow controller system keeps the flow consistent until the very last drop. There is a handy window in the barrel of each pen so you can keep an eye on the ink level, ensuring you never get caught out with an empty pen. The 0.7mm tip gives a 0.5mm fine line.
