Usually a shoe box filled with random pieces of broken items like watches, lighters, old cell phones, remotes, mp3 players, etc kept by a person on crystal meth. It is brought out when the owner is "gakked out" and in need of something to do so they try to "fix" the random items in the box but rarely, if ever, succeed. Will sometimes contain tools like screwdrivers or a dreamed, and random items they found on the ground somewhere like pieces of wire, chess pieces, coins, nuts, bolts , screws, razors., anything small that they think they can repair or use to repair something else. Generally kept in a closet, under the bed, or in a shed. A better alternative for tweakers to picking at their faces.
Justine is on one again and picking at her face, Quick, get her gack box to keep her busy
