100" invisible zippers are used for light weight fabrics made into duvet covers.
These are #2 invisible zippers. Each zipper is 100" long, closed bottom with one pull.
#2 is the lightest weight invisible zipper, #4 is the medium weight & #6 is the heaviest weight invisible zippers.
The #4 pulls will not fit on these zippers. I do not stock #2 pulls in bulk. I do have a few white, tan & black #2's which are here in the "GARAGE SALE".
There is nothing wrong with these zippers. I'm just reducing inventory so that I can move.
