Space Shuttle spacefood pack labeled "Tofu w/ Hoisin Sauce, 1311 BLY418," 4.5″ x 8″ x .5″, with a small circular piece of Velcro on the back. Unlike the unappetizing freeze-dried food products of earlier space programs that required rehydration, this type of thermostabilized food pouch just needs to be heated before being eaten. In fine condition.
