This is possibly one of my favorite products I've purchased from simply zero. Before this, I had tried tooth powder and my husband and I didn't love the consistency and it didn't feel as sanitary to dip your brush or sprinkle over it. These are perfect! We especially love them for travel and backpacking. We take exactly the amount we need and it's not a liquid we have to take out for TSA! They taste good and clean well and you know exactly when you need to buy more. I can't recommend enough!
