Uni jetstream retractable rollerball pens contain super smooth, quick-drying ink in a modern design with a smooth rubber grip. They combine 3 ink colours in one pen so you can easily colour code your notes without reaching for your pencil case. Each colour has a 0.7 Mm nib which is great for your everyday writing and drawing. The ink is quick-drying so it's ideal for left handed users or writing on the go. Each colour writes super smoothly without clogging thanks to the rollerball nib. The soft rubber grip is comfortable to hold. You can retract the colours when not in use to prevent damage to your pen. The barrel is black and contains 3 ink colours including black, red and blue. This pen can be refilled using uni jetstream rollerball refills.
