Review on ZipperStop Wholesale YKK® Solution Assorted by Kristen Reid

Seemingly strong. I just received them so I can't say how they will hold up. My problem is that I need a retainer, not a regular stopper. When I try to buy a #7 retainer, even Zipperstop doesn't have one. They have #5, #8, #10, but no #7 to match their own Blitz. I even went to their website, no stop #7. Maybe #8 would suffice? Who knows, because they don't give instructions. They also say that if an email contains words, incorrect grammar, punctuation, or the wrong sound, don't reply to it, it's foreign. This is what the tongue looks like on the back of the card. It says "Made in the USA". I doubt it.
