Title: Disappointed in wear over time
Review: I purchased twelve cups in white six years ago. I love the fact that they are shaped perfectly so you don't drip when you drink, and they are heavy so they retain heat well. However, after six years of use (which I realize is a long time) the inside of the cup has lost the hard shiny part of the glaze and when you stir with a metal spoon, it makes metal colored marks inside the cup and stains easily from coffee and tea. I am disappointed because I expected longer usage than this.
