I haven't gotten any titan
coils in quite awhile. Do they still come in the plastic packaging ? If I'm remembering correctly (and dats hard fer a monkeys mind you)

I took a sharpie when I got them and marked the plastic wrapper as soon as I got them. When I went to use them I knew what they were. If you have a PV that reads resistance you can check them that way too.

sorry if I didn't answer your question
Some one wiff smarts will be alongs soon Honeys to answer you
