Reproduction paper RZM tags. These are laser printed with toner on old paper stock and then stamped. They will not bleed when wet. You will need to apply glue to attach the tags.
This is a very generic RZM tag, many others were purpose printed for specific items, but this you could put it on a number of items. Just another fun little detail that maybe only you will ever know is there but, sometimes, those are the best.
Please select quantity: 4 labels for $2 or a 10 pack for $4
