Do Not Buy!  Stained my children's mouths, lips and toothbrush heads.
Terrible product.  First the tablets came in a plastic bag without any instructions.  Second the tablets not only stained my kids mouths, tounges, and lips...their toothbrush heads were also stained.  I would rate them less than one star if possible.  I will be throwing these right in the garbage.  I would NOT recommend buying these, they are NOT like the ones I used to get from the dentist office when I was a kid.
