Not what they say they are
I bought this set of replacement brushes for my Oral B toothbrush because the ones we had were too stiff, and I needed something softer. These were described by the seller as being soft -- specifically, "sensitive toothbrush heads," but they are anything but that. The bristles are a not-very-soft vinyl of some kind -- I thought they would be super flexible, like the silicone pastry brush I have for my kitchen, but they are very, very hard. I can't use them because they make my gums sore. I would not recommend this product, especially if you have sensitive gums.
