Artline Whiteboard Markers have the brightest ink to ensure that anything you write stands out and pops out of the Board. The unique dry safe ink formula allows the cap to be left off for up to 48 hours without drying out. The alcohol-based pigment ink in the Artline has a non-offensive low odour and provides dense bold colours. Suitable for use on electronic whiteboards. If you’re in a high-stakes meeting, high-school classroom, or running a university tutorial, if there’s a whiteboard up-front, it is highly recommended to use a high-performance Artline whiteboard marker. This 5MM CHISEL NIB BLUE Whiteboard Markers have a smooth flow from the beginning to the end.
