They have the perfect grip to use to floss between tightly spaced and crowded teeth. This sling-shot handle is unique and better for me than the handles that look like hacksaws.I bought these at Walgreens. Great price! Great habit!I have tried different brands, but, nothing is as good as Glide. They are sturdy, hold up well, get between even the tightest of places. If you have a difficult time getting the string floss to your back teeth, look no further. Each floss stick has a ribbed grip on the end so you can get a good hold on the floss stick. The floss reaches to your back teeth and gum and cleans in between.
