Masking tape's

1/4" x 60 yards

Everyone's favorite "Green Tape" but custom cut to 1/4" wide.

I personally use this tape for my cut off lines when doing mid-soles and to cover air units on 3's and 4's. Because of its smaller width its flexible enough to be able to split a whole mid-sole with one single piece instead of using multiple small pieces to be able to go with the curves on mid-soles.
