These markers write with a clear ink that darkens as it dries.
This white chalk marker is very light, for a more opaque white for nonporous surfaces try the RayMay Fluorescent Board Markers - 2 mm.
Unlike whiteboard markers that can erase only when used on whiteboards, these liquid chalk markers can erase from dozens of non-porous surfaces. Use these great markers to write on white boards, black dry erase boards, windows, mirrors, filing cabinets and more! You can even make any poster into an erasable surface when you write with this chalk marker. Plus, your hands will never get dusty. Not suitable for chalk boards as marks may not erase cleanly from the porous surface.
This set is great for restaurants and store owners. They are dry erase and wipe clean with any cloth or paper towel. This line is the first of many to come from the Japanese Kuretake brand.
