A cutaway illustration of a coffee maker reveals its inner mechanics in bright amber and gold against a dark charcoal ground, with "Coffee Science" emblazoned in bold orange lettering across the top. Labeled components and flowing liquid streams show the brewing process in technical detail, creating a playful intersection of chemistry, engineering, and the everyday ritual of morning coffee. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
