Nylon Topline/Seam Tape
This flexible nylon tape helps reinforce your shoes or bags at toplines and seams.
The 1/4" and 1/8" tapes are woven nylon seam tapes. The 1/2" width cream is also a nylon seam tape. You can use the 1/2" width cream one under shoe lace holes, for example, to reinforce that area.
The 1/2" black is a SEAM tape, which is used for the center back seams, for example, over the stitches. It doesn't feel sticky, but when you apply pressure, with hammering, it will stick.
