These four flavoured butter knife packagings are designed by Yeongkeun Jeong. The idea is to package butter in a very convenient single-serve way, so it is perfect for traveling or picnics. The wooden knife lid is used to spread the butter without carrying an additional cutlery.
As a fan of butter, I love this idea and I think this kind of all-in-one concept can be extended to yogurt and ice cream packaging designs.
