Hi,
Somebody is helping me make a backpack – for the zips, we ordered some of the Riri Aquazips from here (Pacific Trimming):
http://www.pacifictrimming.com/default/riri-zipper/waterproof-aquazip/riri-waterproof-ast.html
However, apparently if you hold it up to the light, you can still see gaps between the teeth.
Surely that's not normal right? Is the above zip the correct waterproof Aquazip that everybody refers to?
Or is this somehow not an issue?
Regards,
Victor
