Mark V Tagging Gun is the newest Avery Dennison gun available. It is the first tagging gun to have an unexposed and retractable needle to minimize operator risk when attaching tags. Each Tagging Gun comes with interchangeable Anvil (pictured) and Tag Holder guards for maximum tagging flexibility and reduced operator risk. The needle is protected until the gun is in use, so you won't have to replace your needles as often! Standard Tagging Gun is most commonly used with general-purpose and heavy-duty fabrics such as jeans, shirts, and outerwear.
