    Good alternative to tubes

    My sister and I have been using duo as a truly workable alternative to tubes of toothpaste-- far less non-compsotable waste and it takes care of your teeth!

    Ditch the tube!

    The tablets foam up nicely with a couple of chews and my toothbrush, leaving my teeth and gums clean and my breath fresh.
