Our wall calendar ships flat in a box. Note that colors may vary slightly from what you see on your device due to differences in screens that cannot be controlled for. VERY IMPORTANT: - Test any marker you plan to use on your calendar in an inconspicuous area to ensure it erases cleanly and completely! - You can find full instructions for our reusable calendars, including what chalk pens I recommend here: https://shopthekaleidoscope.com/pages/reusable-wall-calendar-instructions-tips - We are not responsible for and cannot issue refunds for damage caused by the markers you choose to use. - Some colors and brands of chalk, dry erase and/or wet erase markers may leave a little bit of "ghosting" (residual color) on the calendar surface after they are erased. So TEST any marker(s) on a small & inconspicuous area on the front of your calendar before writing all over it. - Note that the back of your calendar is not coated with matte lamination and is not erasable. Marker testing should occur on the front of your calendar in a small, inconspicuous area. - Wait for any marker to dry completely before attempting to erase it off to reduce the possibility of ghosting. - To clean your calendar, wipe it gently with a damp cloth and then dry it immediately with a dry cloth. Do not use a magic eraser, scrub pad or anything else that is abrasive on your calendar as it could damage the matte lamination. - Traditional ballpoint or ink pens will not write well on the smooth, matte laminated surface and are not erasable.
