The tea cup is fully functional, plus green tea always looks best in a green, white or clear cup. It looks extremely unhealthy in a blue cup, as I've learned by unfortunate experience. Given the weight, you could also kill somebody with that cup in a pinch. Both the cup and the tea came from Gainesville, by the way, the cup from Kanapaha and the sencha from an Asian _supermarket_. Not a hole-in-the-wall little Asian market, but a Publix-sized store with automatic doors and shopping carts. On the downside, it was a Korean store, not Chinese or Japanese. Kimchee, anyone?
