How do you tell when sushi is done? Well, if it werenâ€™t a trick question, one might take the spaghetti approach and throw a piece at the fridge to see if it sticks. In the case of the DCI Gifts Mini Sushi Magnets, it would. While that method may be tried and true, as any college kid will tell you, the test spaghetti doesnâ€™t always make it off the wall and into the trash. Modern art has to start somewhere. But anyways, back to the fish: sold as a set of ten, the refrigerator magnets offer all of the fun of having fish stuck on the fridge, but without any of the associated smell.
