It keeps singer's mouths shut for the 8 hour trip to the next town
I like the white gaff for labeling purposes
When you have lots of electronics, it makes a very good labeling surface for anything
I especially like using it on my cables
It's expensive but I got a box full of half used rolls for free
Gaff is much more managable than "duck" tape
It has a less reflective surface and the sticky part leaves behind less of a residue (which often dries to a powder in the good sh!t)
Plus, it tears very easily in the hands
