This is the largest & strongest invisible zipper that I can find on the world market.
25 yards of 1 color on a roll = $2.35 x 25 = $58.75
35 matching pulls = $.75 x 35 = $26.25
Total = $85.00
Pulls or Heads are NOT on the tape. #6 invisible is easy to put your pulls on.
What does the #5 or #6 mean?
It's the mm size when the zipper is closed. So Brand X is 5mm across the closed coil. Mine is 5.8mm across the closed coil. Every manufacturer has a different machine that makes the coil, different tape to sew the coil on to, different SIZE or diameter of nylon filament to make the coil from.
My #6 zipper heads will fit on others tape, sometimes...... If you are ordering just heads to fit tape you already have, tell me the manufacturer or where you purchased the other heavy duty invisible zipper tape & I can tell you if they will fit.
