Husky brand tool box with 12 removable parts bins. Top layer consists of 13 separated bins, 12 of them are removable. The center tray is fixed and does not come out. Trays are various sizes and all are 2.5 inch deep. Main cavity is 18.75" x 9.75" x 7.25" deep. Purchased at Home depot a couple years ago and it quickly became my electrical toolbox. Now I've got a bigger one. Its in great shape with very little wear and tear. $20 and its yours!
