    Good for your teeth and good for the environment

    I've been using these Duo tablets for a week or two and I love them. I'm letting my husband finish the last of our toothpaste in a tube and then he will switch over as well. No more tubes going in the landfill, no more chemical fillers; just a cute little brown bottle and recyclable refill packages when we need more.
