The Bi-Office Drywipe Markers' long-lasting bright colour stands out on whiteboards. The non-toxic ink is easily wiped off and can be left on a dry-erase surface for weeks without causing any damage. Its fast-drying formula prevents you from lingering on ideas that do not matter. Unlike permanent markers, they can be used to write on whiteboards without ruining the surface or leaving a mess. You won't have to scrub off smudges or worry about staining. These markers are all vibrant and have no noticeable smell. They have a good grip and a narrow tip, which makes it easier to write and draw with especially fine details. The lid closes properly, keeping the marker from drying out. Accessories like these allow you to use drywipe whiteboards to their full potential. Green dry-erase markers, supplied as a box of 10 markers.
