A Starbucks photo cup is a reusable cup which has an outer clear plastic body, and an inner layer that holds the drink, giving you space to slip art or photos in-between. You simply unscrew the bottom of the cup, slip your art between the layers, and screw the bottom back on. Very simple, very easy. And I did mention “reusable,” right? Better for the environment than using and throwing away plastic cups every day.
Some people like to slip in a picture of their kids or friends, or something of their favorite hobby or interest, a cool pic they took on last vacation, etc. I like the hobby bit; but I like to really make it kick.
