Faber-Castell 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 12+ hours without drying out. Made with super strong and bold colours. Low odour-ink dries fast once applied and can be dry-wiped with no residue left behind. 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 Faber-Castell whiteboard marker. This 2 SIDED INCLUDES MARKERS WITH ERASE Whiteboard Markers provides a wide line with smooth flow from the beginning to the end.
