This set includes 12 brightly colored calendars (made from durable cardstock) that each measure 18” x 12”. The name of the month is labeled at the top of each poster, and 35 blank white boxes make up the calendar. Use a wipe-off marker to write in the dates and other events, appointments, assignments, etc. Calendars have a glossy coating for durability and use with wipe-off markers. Display all of the calendars at one time to show a full year or use each month’s calendar individually. ~ Rachel
