Mechanics 3 Part Peel and Stick Tickets are used by mechanics and automotive body shops to track the amount of time worked on jobs. There are three separate layers, with carbon copies between each. Using a time clock or time stamp, the top layer has 9 peel away labels which can be attached to work orders. The middle copy is used for office and payroll purposes, and the bottom copy is a heavier stock used for the mechanics time records.
