Since 1950, BIC has built its reputation on making top-quality writing instruments for the best value. BIC uses a gel ink system in these erasable BIC Gel-ocity Illusion pens based on heat-sensitive technology so when erased with the eraser end, the ink vanishes without a trace. That means you can glide these BIC Gel-ocity Illusion pens across the page without worrying about making any mistakes. This pack contains four gel pens with turquoise, purple, pink and orange ink. A guiding principle at BIC has always been to combine function and design, so they have a comfort grip made for anyone who writes up a storm. The tinted see-through barrels match the colour of the ink and their street art-inspired design creates quite a cool illusion.
