Rollerball gel ink pen The Signo Gel Pen is perfect for adding colour to your notes at home, work or school. The pens use uni Super Ink, a gel ink that is quick drying, water resistant and doesn’t fade. With a vivid range of colours and an eye-catching opaque pigment the Signo Gel Pen is also a staple for crafters. The pens come with a clear barrel, so you can see when they are running out and each has a colour-coded cap. The 0.7mm nib gives a line of 0.4mm and this pen is available in black, blue, red, gold, silver and white. UNI SUPER INK Featured in all uni-ball pens and most prominently the SIGNO series, Super Ink is an archival-quality pigment ink that offers extraordinary levels of water, chemical, and light resistance. In comparison to standard washable inks, uni-ball’s acid-free Super Ink stands the test of time by embedding itself into the fibers of paper – making the ink permanent. Due to larger particles, Super Ink’s unique pigmentation creates more legible writing that lasts a lifetime. Perfect for writing checks or signing important documents, our patented Super Ink is ideal for anything that needs to stay put.
