These new leather Luggage Tags for the small black Featherweight cases are invaluable for telling which machine is which. Whether you are attending a retreat with other Featherweights or you are trying to identify machines in your own personal collection. These tags have a slot for a business card sized card. You can add your contact information or serial number and birth year on the machine. We all want our machines to have the best, let's treat our cases the same way.
