Doesn't say the pens are safe for tooth enamel. Also need to know if they are returnable if not satisfied. Thank you.

Peroxide contained in teeth whitening solutions can cause serious irritation. At-home products generally contain a low-concentrated solution, but about half the people surveyed report that they still experience some discomfort from the procedure. Be sure not to leave products on your teeth for longer periods than recommended. If you are feeling pain or severe tooth sensitivity, you may wish to dilute the solution or choose an alternative product.
