BIC 4-Color Ballpoint Pen with Black, Blue, Red & Green Ink - Perfect for Office, School & Note Taking

BIC's Multipen 3+1 goes one step further than the classic 4-colour multipen. You get 3 ballpoint colours - black, blue and red - and a pencil in one pen and it's refillable too. All you need do is push down the side button for the colour you want, and retract it by pushing down any of the other buttons. To use the pencil, extend it as normal and then use the push button to expose the lead and it is topped with an eraser.

Grippy, silver-coloured barrel.
