Talk about delicious bookmarks! Sandwhich Tag is the latest work of Japanese design trio Yuse Design. The sandwich ingredients, which function as bookmarks or post-its, come in a variety of “flavors” including the standard B.L.T., or the veggie version. But, you are also given the awesome option of loading up on just bacon. The more notes you take, the more appetizing your book becomes! It’s a similar concept to the Green Marker, except for omnivores.
