These monthly schedule refill pages are 6-hole-punched and designed to fit pocket-sized system binders like the Raymay Davinci System Binder (Pocket Size) and the Lihit Lab System Binder. The pleasant, cream-colored sheets are thin to reduce bulk, yet durable and resistant to bleed-through. They are made of Tomoe River paper, which is known for its smooth and velvety texture. These versatile blank monthly calendar pages give you complete freedom and control to fill in desired months and dates. Two facing pages make up one month. The column down the left side lists all the days for you to make brief notes or marks, and there is a memo box for extra notes. This pack contains 30 sheets.
