Designed by our very own William Rowe, the calendar rather cleverly maps the 29.5 day lunar month using a CMYK colour fade that's called aChromo. Entirely coated in plastic, so you can write whatever you want on it with a non-permanent marker (which is supplied), the calendar measures 120cm x 42cm and works either landscape or portrait depending on which side you choose. Straight up Protein style with a side of practicality.
