I have purchased the product before and have purchased multiple packages for a great deal. My 3 year old son loves to floss with these. He started using them (with parent's help of course) at around 2 1/2 years old. He loves that he can choose a color and can do it him self at first and then we would help afterwards. Grape flavor was a nice touch. Floss is sturdy and cleans well. Can also be used by adults. Highly recommend.
