Shelf Labels and Tags

A4 perforated shelf tags can be placed in the feed tray of your standard A4 laser or inkjet printer or photocopier. You can use whatever software you require to print your product information/prices/barcodes and then the shelf tags can just be torn away along each perforation and the shelf tag can be inserted into the shelf runner.
