These brushes are my favorites: they go in every corner and uniquely clean the areas between the tooth and gum. Better than Tonigencyl better than the pub !!! Top, at 15:00, is to feel that we still have smooth and clean teeth. Me, that's all I ask! And there the contract is completed. In addition, fast delivery and packaging nickel, worthy of Amazon reputation. The stated time was fully respected. A choice without hesitation!
