Revolutionising the world for 4 Colours pen fans one click at a time. Now you can have it all with BIC 4 Colours 3+1HB pen. It includes the classic blue, black and red ballpoints, but the green pen has been replaced with an all-purpose HB pencil lead. World-famous for being able to write a line up to 2km long, the 1.0mm ballpoint pens feature the same smooth dependable ink flow you’ve always loved. The 0.7 mm pencil is perfect for detailed notations and sketches, plus the push button includes a built-in pencil eraser. When the levels start getting low, refilling the ink and lead is a cinch. Just unscrew the barrel, pull out the cartridge and push in a new one. A 4-in-1 pen that saves space and time.
