With the Wonder Zip Zipper Threader, threading the slider onto an endless zipper becomes child's play! Suitable for all types and sizes of zippers.

This is how it works: Slide the Wonder Zip over the edge of a table top and insert the zipper / slider face down into the slot on the top. Thread the two halves of the zipper into the zipper at the same time, forming a 90° angle. The coil of the zipper faces the table top. Pull the zipper backwards evenly. Done!
