Earth Green 120-Day 4-Month Horiztonal Dry/Wet-Erasable Wall Calendar Kit: 24 in. x 36 in. Dry AND wet erasable! The best of both worlds. :-) Markers will not ghost or stain. Our special film surface performs better than all of the others. Our calendars easily unroll and lay flat. Installation is a breeze! Thicker calendars stay curled making installation a nightmare. Once installed, calendar thickness is irrelevant! Recyclable! We make the only erasable calendars that can be recycled with household waste. 24" x 36" horizontal. Date blocks 2-5/8" wide X 2" tall
