Take a look at these handpainted lunch bags. They're painted (one each day) by a dad, on his lunch break, for his kids. His Tumblr is a collection of these lunch bags, from the "snagon" pictured here to the "emocorn" below.
See more awesome lunch bag art (such lucky kids!) at this dad's Tumblr. He has a store, too, where you can buy some of his most popular designs.
