Use where a standard tag is not suitable & an original & two copies are essential. Each unstrung tag features a detachable top sheet & a layer of carbon paper, so you can keep the completed tag attached to the item in question & file a copy away. Attach the tag to the relevant item in your inventory & file the information away in two separate places to ensure that your data is safe. Each tag & its top sheets are identically numbered in red for easy reference. The reinforced eyelets are extremely sturdy. Tags are numbered consecutively.
