    Excellent for patients with wide embrasure spaces!

    I LOVE the black color of the floss, really allows you to see everything coming out from between the teeth! Personally, my teeth are pretty close together so I found this to be a little too wide for my liking, however would highly recommended to patients with larger spaces between the teeth, almost reminds me of super floss!
