CONVENIENT SIZE: Our perpetual calendar is the perfect size for displaying on your wall or keeping in your desk drawer. Measuring 4.25x11", each single-sided page features one month. DATES AT A GLANCE: Each monthly page makes it easy to see your special events at a glance. Keep track of birthdays, anniversaries, and holidays in one convenient place. Write it in once and use it year after year. No more copying information from calendar to calendar. QUALITY & DURABILITY: Our calendars are made to last. The sturdy 130# front and back cover protects the inside pages and keeps the calendar flat. Inside, you'll find each monthly page printed on 100# cover stock. No flimsy paper here. The thick paper helps resist bleed through.
