This marker holder is able to hold up to 4 Expo fine tip (Skinny) dry erase markers. This version measures 66mm long, 102mm tall, and 25mm wide. The design is recessed into the surface making it perfect to carry around in a pocket. My design makes sure to grab the cap, while still allowing for the removal of the marker. The marker holder comes equipped with 2 powerful rare earth magnets to make sure it sticks to any white board (or other steel surface). The magnets are flush mounted within the holder to make sure they do not snag anything while being transported. Available in a number of different colors and customizable with your name or even call sign. Does not come with any markers. Additional Colors available on request
