The purpose of the bullet has not been revealed to me right away. When questioned on the manufacturer wrote to me that one can be explained by color markers that are placed in the calendar (z. B. for vacation, certain individuals, projects, ...). Sounds sensible, and I'll get with such markers probably.
The only small snag is that the planner is folded. But it is indeed in the product description that only rolled with order for 4 planners will be shipped. Therefore, no deduction.
