One order includes 4 Poster Strips (one for each corner)
Command Poster Strips are the best way to stick your calendar to the wall without making holes. They are a strong adhesive that holds the paper and the wall well, but they leave no residue when you take them off a year later. Just pull straight down on the foam circular tab, the strip will stretch & remove harmlessly from the wall. Not as cool as the bulldog clips, but still a good option!
