These people offer a range of cold-pressed juices that they'll deliver, chilled to your door. Their speciality is a six-juice-a-day cleanse that costs around 200rmb a day. For that they'll deliver six bottles of fresh juice to you each day. The juice has everything your body needs in the way of vitamins and nutrients. You just drink the juice instead of solid food.
