My aunt bought them here in Toronto for hum...$ 90.00 CAD with 82 strips (Lower,Upper)

My sister bought some of the Rembrandt whitening kit, I used it like once or twice...problem is that I don't brush my teeth til I go to bed, and they (the mouthpieces) need to be on an hour after your teeth are cleaned. We'll see how it goes.
