No, Root works with regular markers that fit into Root's pen holder, perfect for drawing on paper.
Root also works with dry-erase markers and does not require a specific brand of markers. Standard width markers (e.g., Expo brand chisel tip) fit into Root’s center pen holder too. Root’s color sensors work on a whiteboard with dry erase markers or on paper with any type of markers. Root Square’s Level 1 recognizes the four standard colors red, blue, green, and black; higher levels give more access to the sensors and flexibility with colors.
