Structured hot drinks with Positive Vibes The Angelica Cup is a programmed cup for tea, coffee, MagicRooty and other hot beverages. Using the Glass & Vibe technology, the glass continually transmits positive vibrations to your drink as it cools. To prepare tea, pour hot water over the tea in an infuser or use traditional tea bags. Place the tea bag or infuser on the wooden lid after steeping. For other hot drinks, simply pour brewed drink into the cup. Enjoy the positive energy with every sip.
