Zipper pulls are for a #5 zipper.
Zipper tape is sold seperatly.
To install the zip pulls to the zipper:
1) Open one end of the zipper by a few inches, as the coil works both ways, it doesn't matter which end you open.
2) Holding the zipper pull, with the round side down, slide one side of the zipper tape up into the slider. Don't pull it all the way through, stop just when it catches inside. Hold this with one hand.
3) Slide the other side of the tape up into the slider with the other hand. Once you feel the resistance from the other tape, gently push both tape through the pull with equal pressure. Once you can see both tape emerge from the other end of the pulls with teeth locked in place correctly, you can firmly pull the zipper pull down.
