Improve the efficiency of Ideation and exchange of opinions In a meeting with a lot of discussions, opinions on the board are often scattered and the boundaries between groups are often blurred. A whiteboard that is "easy to summarize" and "easy to understand" is needed. Against this backdrop, we developed the "parent turtle" and "child turtle" hexagonal whiteboards to enhance visibility. The hexagonal shape allows grouping without being upside down. Furthermore, the large number of sides makes it easy to express the relationship between the hatchlings.
