Hi George,
There is a lot of embossing tape made-in-China on the web for sale.
But I have been lucky to find enough NOS inventory on eBay that is made in the USA or in Belgium...back in the day. I think I have enough to last my lifetime, now.
My label maker must have been very lightly used. The cutter blade is very sharp and the special cut on the end of each label makes removing the backing plastic so easy.
While I went to college, I worked full time as an electrician/apprentice for 4 years. I think I have made about a million of these labels in my previous life. We used to tag each outlet and light switch cover plate with a label to indicate Panel No. and circuit breaker number. Used black tape for normal power and red tape for power on a generator service.
Using this tool now, after so many years, brings back fond memories of my mentors in that field and then I remember all of those fellows have more recently passed away. I am a better person for having had worked with them.
