Vivid Sylk Premium Quality PTFE Dental Floss Threader Slides – For Bridges, Implants, Braces – Box of 1,000

Very similar to the Gum brand threaders. The material seems to be slightly thicker to me and I can feel the seam, but that hasn't bothered me. They are equally effective and easy to thread the floss through. These were way less expensive than Gum and I would buy again.

Great price for large quantity
