R-TAPE Conform 4075RLA 100YDS Lenght, for Sign Makers (6.5)

Is the "12 inch line" roll 12"x100yards?

Does it have the 4075 written inside the roll? I ordered some from somewhere else and it has nothing inside the roll and will not pick up the vinyl.

What's the difference between your "r-tape conform 4075rla" and the "rtape 4075 conform high tack" i'm about to buy, besides it's "the world's best"?

Will I be able to use this to transfer letter on balloons
