Buyer beware- they stain your sink!
I was not aware when I purchased these that my sink would turn pink… They do state in the directions to keep your water running and wash immediately after use. We did this, but my sink was still pink! It took several products and a ton of elbow grease to get it back to its normal off-white color. It works as advertised as far as staining your teeth and showing you where to brush, but just know you will be cleaning your bathroom for a while after using.
