Packaging design is one of my favorite things to use as inspiration when I am not motivated. As a product designer, packaging is one of the most important things of the development of a product and ultimately the final look of the item. You can't have an amazing product and have a wick packaging! And, it doesn't have to be an expensive box with amazing materials and printing processes (even thought this would be ideal but it's not realistic all the time). All you need is a clean presentation with great character. And, what better way than giving some character to a package than using hand lettering, it just makes it that much special.
These are some samples of packaging I love that incorporate hand lettering but keep the look very clean and simple.
