*by C***R on November 6, 2025*

First impression in wrapper they looked like thin not quality heat shrink. But after opening up and cutting to length and heating on my new battery cables I made, this stuff is super thick and good quality sealer. Shrunk at least 3 to 1. I bought 2 more sizes and have used the larger ones. Very happy with this heat shrink.
