Revolutionize the world of 4 Colours pen fans with every click. Now you can have it all – with the BIC 4 Colours 3+1 HB pen. While it includes the classic blue, black, and red ballpoint pens, the green pen has been replaced with a multifunctional HB pencil lead. The 1.0 mm rollerballs are world-famous for their average writing length of 2 km and feature the same smooth, reliable ink flow you have always appreciated. The 0.7 mm pencil is perfect for detailed notes and sketches, and the push button includes a built-in pencil eraser. When the ink and lead levels get low, refilling is incredibly easy. Simply unscrew the barrel, pull out the cartridge or lead, and insert a new one. A 4-in-1 pen that saves space and time.
