The box measures 6-1/4" wide x 3-5/8" deep x 2" tall. The zigzagger is 5-3/4" long x 2-3/4" wide x 1-3/4" tall. The left front corner of the box is push in a bit. The booklet is folded in half so that it fits into the box. The actual zigzagger has a tiny scratch in the enamel. There are four different "gears" to change the zigzag design. Even the wax paper that wrap the zigzagger and the cardboard inserts are all there!!
