in fact, so does one of my friend's when I let her try one. She quickly took the small container I gave her and filled it right up :D These are stronger than some others I have bought and don't fray when you are using the flosser part. I have had so many start to fray and end up with small pieces of string between my teeth in the past. Not so with these. I really do love them and always have them on me. The pick part is great for getting between my teeth and helping me get that annoying piece of whatever out from there. I am so glad to always have these on hand!
