The ultimate behavioral therapy for the compulsive filler of junk drawers - the drawers of this puzzle are so difficult to open and fit back in that there is no way you'll want to fill them up with scissors, rubber bands, old pictures, stamps, batteries, dried up glue tubes, leaky pens, screws, plastic pieces, paper clips....you get the point. Removing the drawers requires a complex series of sliding movies and seems almost impossible, until you are faced with the even harder task of sliding them back in! Contains four wooden pieces that interlock inside the box. Dimensions: 3 1/7" x 2 1/3" x 3 1/7"
