"Buy One Get One Free" is a common sales promotion known as BOGOF in the marketing industry. What if the BOGOF technique is not for improving sales, encouraging consumers to buy more, and increasing waste? What if it is about other values rather than consumption. BOGOF Mirror is inspired by the consumerism culture in the USA. It is the spirit of the American supermarket to drown consumers with sale slogans, maybe that is why we always buy more than what we need. BOGOF Mirror contains two mirror pieces that would be separated from the middle. It is possible to attach and convert them to one piece again through the magnets placed inside the mirror bases. The base is made of 3D printing bioplastic material.
