Except for almost $15 postage charged for the $8, 1 pound spool of Safety wire, the experience was great.

I actually am using this in my protected masks for the pandemic. The wire is easy to work with, easy to cut and easy to manipulate.

Exactly the safety wire I was seeking. The container however is a cardboard tube container and would have wished that a plastic longer lasting container would have been used instead..

Not much to say... safety wire is safety wire (at least, I assume/hope it is as I dont have a metalurgy degree to confirm). But ACS support and speed of delivery were awesome, as always... and the price was good.
