This is a game changer. All other toothpastes should pack up and close shop. I don’t know what I
Was using before, but it was not toothpaste. This is the only toothpaste you should be using.

Great tasting and our son's favorite treat!
Flavor Name: Natural Fruit, Size: 8 Ounce (1 Pack)
Our son loves these! He asks for them every day! For being no sugar they taste great! My kid is obsessed! We have bought these several times at this point and while I can not say whether or not they work in terms of vitamin c, I simply wouldnt know for sure, they do work in keeping him calm in public places.
Its great that there is no food dyes in the ingredients too so that I can feel good giving them to him. In terms of quality, we have yet to recieve any broken lollipops or loose, candy or open wrappers so that is great!
The paper sticks to start to peel apart, but usually that's by the time the lollipop is finished.
I think the amount we paid for what we got was well worth it.
